Figure 1. Temperature-Dependence of Kidney Stone Presentations for the Overall Population of South Carolina.

Figure 1.

A) Relative risk of kidney stone presentations associated with maximum daily wet-bulb temperatures for the overall population cumulated over a 10-day lag period, relative to 10 °C. The beige and pink areas represent the moderate range of daily temperatures, respectively. The black line is the RR and the surrounding gray area the 95% CI. B) Lagged RR associated with maximum daily wet-bulb temperature at the 99th percentile and kidney stone presentations over a 10-day period, relative to 10 °C. The red dots are the RRs and the whiskers the 95% CI for each day following exposure. Natural cubic spline knots were placed at the 50th and 90th percentile of the temperature range and 2 knots were placed at equal intervals in the log scale in the lag dimension.
