An association of solar radiation with OHCA events. Upper figure represents the incremental effect of exposure to solar radiation above the 90th percentile (73.2) as compared to the median value of 29.7 over the course of 72 h prior to the event onset. The figure in the middle shows the cumulative effect of the respective exposure. The bottom figure represents an incremental effect of exposure to solar radiation at 24 h prior to the onset
