Table 3

Cumulative odds ratios estimated for daily stroke cases (95% confidence interval) associated with extreme heat exposure during the night [97.5th percentile of hot night excess (HNE) distribution] for the overall study period and the periods 2006–12 and 2013–20

	Entire period	2006–12	2013–20	P-value^a
All cases	1.14 (1.01–1.32)	0.99 (0.91–1.08)	1.33 (1.18–1.50)	.03
Haemorrhagic strokes	1.04 (0.83–1.35)	0.98 (0.85–1.15)	1.21 (1.02, 1.48)	.48
Ischaemic strokes and TIA	1.16 (1.02–1.35)	0.99 (0.91–1.09)	1.32 (1.16–1.49)	.03

TIA, transient ischaemic attack.

^aSignificance test based on the difference between OR estimates in 2006–12 and 2013–20.
