  1. p-values are interpreted as follows: < 0.10 significant at the 90% significance level; < 0.05 significant at the 95% significance level; < 0.01 significant at the 99% significance level. Odds ratio (OR) represents the odds of belonging to a hot spot: OR > 1 indicates increasing odds of belonging to a hot spot for each unit increase in the independent variable, OR <1 indicates decreasing odds of belonging to a hot spot for each unit increase in the independent variable. Lower confidence limits (LCL) and upper confidence limits (UCLs) are provided.
