Building Resilience to Climate Change: Pilot Evaluation of the Impact of India’s First Heat Action Plan on All-Cause Mortality

Table 1

All-cause mortality incidence rates (deaths per 100,000 population-years, with 95% CIs) for the pre- and post-HAP periods for the categories of any warning, yellow warning, orange warning, and red warning, respectively, as well as incidence rate ratios comparing post-HAP to pre-HAP IRs and 95% CIs.

Period	Any warning (>40°C)	Yellow warning (41–42.9°C)	Orange warning (43–44.9°C)	Red warning (≥45°C)
Pre-HAP IR (95% CI)	819 (788–850)	776 (753–798)	857 (830–883)	1244 (789–1699)
Post-HAP IR (95% CI)	775 (750–800)	708 (674–741)	773 (746–799)	908 (843–973)
IRR (95% CI)	0.95 (0.73–1.22)	0.91 (0.62–1.34)	0.90 (0.60–1.35)	0.73 (0.29–1.81)
