Number of ICD ATP and shock therapies and rates per patient year stratified according to sex

	Number of events (rate per patient year)		Female vs male
	Female	Male	RR (95% CI)	P value
Inappropriate ATP	405 (0.36)	1378 (0.28)	1.22 (0.42‐3.59)	0.715
Inappropriate shock	120 (0.11)	848 (0.17)	0.64 (0.36‐1.13)	0.121
Appropriate ATP	1116 (0.98)	11849 (2.42)	0.37 (0.14‐0.97)	0.043
Appropriate shock	526 (0.46)	1647 (0.34)	1.95 (0.46‐8.32)	0.369
