Figure 6.
Percent difference (PD) [95% confidence interval (CI)] for the relationship between extreme cold-heat ambient temperatures and occupational injuries in Spain, 1994–2013. Cold effects refer to temperatures in the 1st percentile of maximum temperature versus the percentile of minimum occupational injuries (PMOI). Heat effects refer to temperatures in the 99th percentile versus the PMOI. Confidence intervals ending with an arrow (heat effects) indicate large intervals that are truncated in the figure.
