From: Driving fatalities on US presidential election days: a reanalysis
Relative risk (RR) estimates for presidential election days and the 100 preceding and following Tuesdays. Red dots indicate RRs for all Tuesdays. Black circles indicate RRs and black dashed lines indicate RR and 1/RR for presidential election days. The proportion of red dots outside black dashed lines is equivalent to the reported non-parametric P value
