Table 3 Subgroup analysis of mortality reported by included studies

Ref.	Subgroups	Result
Sreenivasan et al[16], 2021	Acute MI only	Significantly higher mortality in severely obese patients as compared to normal patients
	Acute HF only	Significantly higher mortality in severely obese patients as compared to normal patients
	Age < 60 years	Significantly higher mortality in severely obese patients as compared to normal patients
	Age ≥ 60 years	Significantly higher mortality in severely obese patients as compared to normal patients
Chatterjee et al[20], 2017	ST-elevated MI	No statistically significant difference in mortality between obese and normal patients
	Non-ST elevated MI	Significantly lower morality in obese as compared to normal patients
	Revascularization group	Significantly lower morality in obese as compared to normal patients
	Non-revascularization group	No statistically significant difference in mortality between obese and normal patients

MI: Myocardial infarction; HF: Heart failure.
