Protocol Version	v15.0 (Living Protocol — auto-updating)
Protocol Freeze Date	2026-03-10
Protocol Registration	Immutable timestamp via GitHub commit history at `github.com/mahmood726-cyber/rapidmeta-finerenone`. Each protocol amendment is a separate commit; the freeze date above corresponds to the most recent protocol-affecting commit. For external registration (PROSPERO / OSF) on submission-bound topics, see the per-topic Submission Cockpit. Per ICMJE 2023, GitHub commit hash + timestamp constitutes a verifiable pre-registration record equivalent to PROSPERO for tracking outcome / eligibility / analysis-plan changes.

Funding Source	No external funding (independent academic review)
Conflicts of Interest	None declared
Contributor Roles (CRediT)	MA — Conceptualization, Methodology, Data Curation, Writing (Original Draft & Review & Editing), Supervision. Per ICMJE 2023: human author takes full responsibility for accuracy and integrity of the work, including all AI-assisted components.
AI Assistance Disclosure	AI tools (Claude / Anthropic) provided: (a) automated audit tooling implementation (internal-consistency, fragility-index, PI-gap, GRIM/Benford, AACT cross-check, PMID DataBankList verification), (b) statistical module implementation (REML+HKSJ primary with DerSimonian-Laird sensitivity pooling, node-splitting, Doi/LFK, comparison-adjusted funnel, CINeMA-lite, POTH, Q-decomposition, contribution matrix), (c) initial drafts of summary text subject to human verification. AI is NOT listed as an author per ICMJE 2023; AI cannot take responsibility for a manuscript. All AI-generated content was reviewed and verified by the human author.

Network Meta-Analysis

Indirect comparisons via connected treatment network

Treatment Network

Nodes = treatments (sized by total N). Edges = direct trial comparisons. Dashed = indirect only.

League Table (All Pairwise Comparisons)

Upper triangle: effect estimates with 95% CI. Green = significantly favors row. Red = favors column. Gray = non-significant.

Live Re-pool from Raw 2×2 (verifier)

Re-pools the trial-level raw event counts in realData using REML random-effects + HKSJ + Cochrane v6.5 prediction interval (t_k-1). Compare the pooled estimate (cyan diamond) vs the published headline (gold dashed). Per-trial rows show the back-transformed RR with 95% CI and RE weight.

Treatment Rankings (P-Score)

SUCRA/P-score measures ranking probability, NOT effect magnitude. Always interpret alongside the league table effect estimates.

Consistency Assessment (Node-Splitting)

Network Consistency (NMA Pro Transplant)

NMA-Pro-style direct/indirect node-splitting with Fisher-combined global inconsistency test (Dias et al. 2010 back-calculation). Star networks (every comparison via a common reference) trigger an explicit transitivity-only disclosure since no closed loops exist to test consistency by node-splitting.

ROB-NMA + Transitivity (Cochrane 2025)

Lunny 2025 BMJ ROB-NMA tool (17 items, 3 domains) with auto-prefill from existing modules + transitivity effect-modifier balance per Brignardello-Petersen 2023 GRADE-NMA Article 5 / Lasch 2025 Res Synth Methods.

Bias & Certainty (Tier 2 Transplants)

Small-study-effects (Doi plot + LFK index, Furuya-Kanamori 2018), comparison-adjusted funnel (Chaimani & Salanti 2012), and per-pairwise certainty (CINeMA, Nikolakopoulou 2020). Tools chosen for k<10 networks where Egger's test is underpowered.

Compares direct vs indirect evidence for each comparison. P < 0.10 suggests inconsistency.
