# Bias Assessor ## Triggers & routing - **Trigger**: bias, risk-of-bias, RoB, evidence quality, 偏倚评估, 证据质量. - **Use when**: `evidence-review` 已生成 `papers/extraction_table.csv`，需要在 synthesis 前补齐偏倚/质量字段。 - **Skip if**: 不是 evidence/systematic review，或还没有 `papers/extraction_table.csv`。 - **Network**: none. - **Guardrail**: 使用简单可复核刻度（low/unclear/high）+ 简短 notes；保持字段一致性。 Enriches the extraction table with lightweight risk-of-bias fields for `evidence-review`. ## Input - `papers/extraction_table.csv` ## Output - updated `papers/extraction_table.csv` ## Contract The table should expose stable RoB columns: - `rob_selection` - `rob_measurement` - `rob_confounding` - `rob_reporting` - `rob_overall` - `rob_notes` Allowed values are fixed: - `low` - `unclear` - `high` ## Script boundary `scripts/run.py` should: - add missing RoB columns - assign a conservative overall score - keep notes brief ## Acceptance - RoB columns exist - all included rows have values - values stay within the fixed scale ## Non-goals - deep methodological critique - rewriting extraction contents
