In this plot there are more points to the left of the vertical line, suggesting heterogeneity caused by either variation in length of observation or publication bias. IRR = incidence rate ratio.

The trend line indicates the degree to which the incidence rate ratio (IRR) decreases as the duration of the post-ban period increases. Figure Legend:
