Risk of Bias Appraisal

An AI-assisted research tool for evidence-linked critical appraisal and risk-of-bias assessment.

Upload a study and prepare an appraisal draft

Select Open Risk of Bias Appraisal below to enter the linked ChatGPT tool. Attach the full-text report and, when available, the protocol, trial registration, supplement, and analysis plan. State the study design, review question, outcome and result being appraised.

The tool can organize a design-appropriate draft and supporting evidence. Verify every judgment and evidence location against the original documents; it does not replace independent review.

What it supports

JBI critical appraisal using a study-design-appropriate checklist.
ROBINS-I for eligible non-randomized estimates of intervention effects.
ROBINS-E for eligible non-randomized estimates of exposure effects.

When to use it

Use the tool to support appraisal within systematic reviews and other research, to organize evidence from study reports and related documents, and to prepare evidence-linked judgments and summary tables for review by a research team.

Method and reference base

Use the current study-design-specific JBI tool, ROBINS-I version and guidance, or ROBINS-E guidance that match the review question and estimand. Cochrane now provides ROBINS-I V2; confirm which version the linked plugin applies before use, and do not label an older-version assessment as V2. Record the exact framework and version used in the review.

Methodological safeguards

Select the framework that matches the study design and review question; observational design alone does not determine the tool.
Check the current official framework version and guidance. Record the tool/version and unit of appraisal.
Ground judgments in the paper, supplements, protocol, or registration, with clear evidence locations.
Distinguish missing reporting from evidence that a bias mechanism occurred. Preserve uncertainty when information is insufficient.
Do not convert item judgments into arbitrary numerical scores or claim a second independent human review unless one took place.

Research support only. This tool does not replace independent human appraisal, protocol-specified methods, or verification against the original studies and current official guidance.

This tool is independently developed by Jithin T Joseph. It is not affiliated with, sponsored by, approved by, or endorsed by JBI or the developers of ROBINS-I or ROBINS-E.
