Forest plot of results of studies included in the meta-analysis. RR and 95% CIs of NHL cancer associated with Formaldehyde exposure. Horizontal lines represent 95% CIs for the study-specific RRs. The sizes of the dots for the individual studies are proportional to the study weight. The pooled RR, which was shown as a diamond, was 0.93 (0.83, 1.04). The middle of the diamond corresponds to the RR, and the width of the diamond represents the 95% CI. The arrows indicate greater or lesser confidence intervals with respect to the reported scale
