Sensitivity analysis	Long-term mortality of PA compared with EH
	Follow-up 3 years	Follow-up 5 years	Follow-up 7.5 years	Follow-up 10 years
Model A	1.97 (1.33, 2.91)	0.96 (0.75, 1.23)	0.86 (0.51, 1.46)	0.95 (0.61, 1.48)
Model B	1.91 (1.22, 3.00)	0.93 (0.74, 1.18)	0.91 (0.55, 1.49)	1.03 (0.62, 1.72)

Model B: “One-stage” meta-analysis that included the study reported zero events in both groups.

Model C: “Trim and Fill” method that adjusted the potential publication bias.
