Cumulative apparent temperature (Tapp)-CVD mortality RR with a 21-day lag (dotted lines show the 95% CI) with a histogram of the Tapp distribution for Puducherry between 2011 and 2020. The black solid vertical line represents the minimum mortality temperature (MMT), while the dotted grey line represents the heat wave threshold at 37 °C. The blue line and red line represent the exposure–response curve for cold and hot temperature relative to the MMT respectively
