COVID-LONG v1: We present a pre-validation composite scoring framework for symptom persistence meeting WHO PCC criteria at 6 months post-index in adults with a confirmed SARS-CoV-2 infection who have completed the acute phase (>=28 days post-symptom onset). Published literature reports long-COVID prevalence 10-30% at 6 months depending on population and definition [Davis 2021; Global Burden Collaborators 2022; NICE 2022], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

HIV-ART-START-ADV v1: We present a pre-validation composite scoring framework for clinical IRIS per INSHI 2008 consensus definition within 12 weeks in adult people with HIV and CD4<200 cells/uL at ART initiation, particularly those with concurrent opportunistic infection. Published literature reports IRIS incidence 10-25% in low-CD4 ART initiation cohorts; stratified by underlying OI [Muller 2010; Walker 2015], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

ALZ-ANTI-AMYL v1: We present a pre-validation composite scoring framework for any ARIA-E event detected on surveillance MRI within 18 months of therapy initiation in adult patients with mild cognitive impairment or mild Alzheimer dementia being considered for lecanemab or donanemab. Published literature reports ARIA-E incidence 10-35% in anti-amyloid trials, strongly modified by APOE epsilon-4 dose [van Dyck 2023; Sims 2023], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

RAD-PNEUM-SBRT v1: We present a pre-validation composite scoring framework for grade >=2 radiation pneumonitis at 12 months in adult patients receiving thoracic SBRT for primary lung cancer or oligometastatic disease. Published literature reports grade >=2 RP 9-28% across SBRT series; lung V20 and mean lung dose remain strongest predictors [Barriger 2012; Palma 2013], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

FEBRIL-NEUT-MASCC v2: We present a pre-validation composite scoring framework for MASCC-style serious complication endpoint at 30 days in adult solid-tumour and selected haematologic-malignancy patients presenting with febrile neutropenia who are being triaged for outpatient vs inpatient management. Published literature reports MASCC score >=21 identifies low-risk with ~4-6% complication rate; original derivation Klastersky 2000; contemporary cohorts suggest item recalibration warranted [Klastersky 2000; Carmona-Bayonas 2015], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

POSTOP-VTE v1: We present a pre-validation composite scoring framework for symptomatic, imaging-confirmed VTE within 90 days in adult patients undergoing major abdominal surgery (open or laparoscopic) with LOS >=1 day. Published literature reports 90-day VTE incidence 1-5% depending on cancer status and procedure type [Bahl 2010; Merkow 2011], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

SEPSIS-MORT-72 v1: We present a pre-validation composite scoring framework for 72-hour all-cause mortality in adult ED patients meeting Sepsis-3 criteria at first measurement. Published literature reports 72-h mortality 5-15% in Sepsis-3 populations with strong lactate and SOFA gradients [Seymour 2016; Raith 2017], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

HEPARIN-HIT-4T v1: We present a pre-validation composite scoring framework for SRA-positive HIT (functional assay confirmation) in adult inpatients with suspected HIT in the 5-14 day window after heparin exposure. Published literature reports pre-test probability calibration of 4Ts: low (0-3) ~1%, intermediate (4-5) ~10%, high (6-8) ~34% for confirmed HIT [Cuker 2012; Linkins 2015], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

DOAC-BLEED-GFR v1: We present a pre-validation composite scoring framework for ISTH major bleeding at 12 months in adult patients with non-valvular atrial fibrillation or VTE on DOAC therapy with eGFR 15-59 mL/min/1.73m2.

METFORMIN-LACTATE v1: We present a pre-validation composite scoring framework for incident MALA within 12 months of the assessment window in adult patients with type 2 diabetes on metformin with eGFR 15-60 mL/min/1.73m2 being considered for continuation, dose-adjustment, or discontinuation.

CAR-T-CRS-GRADE v1: We present a pre-validation composite scoring framework for development of ASTCT grade >=3 CRS within 14 days of infusion in adult patients with relapsed/refractory B-cell lymphoma or leukaemia receiving commercial or investigational CD19 CAR-T products. Published literature reports grade >=3 CRS rates 10-50% depending on product and disease burden [Neelapu 2017; Schuster 2019; Maude 2018], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

ICI-MYOCARDIT-RECHAL v1: We present a pre-validation composite scoring framework for recurrence of immune-related myocarditis (any grade) or new MACE attributed to ICI within 180 days of rechallenge in adult solid-tumour patients who survived an ICI-attributed myocarditis episode and are being considered for rechallenge. Published literature reports baseline incidence 0.

ICI-PNEUM-RECHAL v1: We present a pre-validation composite scoring framework for recurrence of grade >=2 immune-related pneumonitis within 180 days of rechallenge in adult solid-tumour patients with documented CTCAE grade >=3 immune-related pneumonitis who are being considered for rechallenge. Published literature reports pooled any-grade irAE recurrence 25-55% with pneumonitis-specific recurrence reported at 25-45% [Naidoo 2017; Delaunay 2017; Santini 2018], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.

ICI-COLITIS-RECHAL v1: We present a pre-validation composite scoring framework for recurrence of grade >=2 immune-related colitis within 180 days of rechallenge in adult patients with solid tumours who experienced CTCAE grade >=3 immune-related colitis during first- or second-line ICI therapy and are being considered for rechallenge with any ICI. Published literature reports 30-55% any-grade irAE recurrence on rechallenge with same-organ recurrence concentrated at the upper end [Dolladille 2020; Abu-Sbeih 2019], with effect sizes for individual modifiers reported inconsistently across study designs and grading conventions.
