Figure 2.

Agent-specific and meta-analytic RRs for the probability of a CEHD sampling result being recorded into IMIS for ‘exposure level ≥ PEL’ compared with ‘exposure level = ND’. Agent-specific RRs were pooled with the random-effects method. Squares represent agent-specific risk estimates (size of the square reflects the agent-specific statistical weight); horizontal lines, the 95% CIs; diamond, the summary risk estimate and its corresponding 95% CI. For (A), the reference level is panel_no: ND; for (B), the reference level is panel_yes: ND.
