Risk of bias Data
Risk of bias in duplicate: RoB 2 or ROBINS-I, with the quotes to prove it
Risk of bias is per outcome, per domain, in duplicate — and every judgement needs a supporting quote the reviewer can check.
You give
The study PDFs, the instrument, the outcome assessed and, for ROBINS-I, the important confounders you defined a priori.
You get
A workbook with the judgements per domain and quotes, plus a publication-ready traffic-light figure (.png, green/amber/red).
How it works
# Risk of bias $ scopetools run rob-dual Model-assisted, with deterministic checks. Two arms per study answering the instrument's signalling questions from the PDF, each with the supporting quote; the domain judgement follows the official algorithm, and disagreements are flagged for you. Nothing is judged without a quote from the paper.
Two independent assessors with different reading orders; the judgement follows the instrument's official algorithm; nothing is judged without a quote from the paper; disagreements stay flagged. The traffic-light figure comes out green/amber/red, publication-ready. The sheet is drafted for two human reviewers to sign — not to replace them.
What it costs
5 credits per study — 12 included studies ≈ 60 credits (US$3).
Charged only when it delivers — a failed run costs nothing.
Credits are shared across every MetaScope tool — buy once, spend anywhere.

Frequently asked questions
- RoB 2 or ROBINS-I?
- RoB 2 for randomised trials, ROBINS-I for non-randomised studies of interventions (confounders defined a priori required for D1).
- Is the judgement final?
- No; it drafts for two human reviewers to review and sign.
- What figure do I get?
- A traffic-light .png, green/amber/red, per domain and overall.
