  Fig. 2.. Kaplan-Meier survival curves for outcomes between SRH satisfied and SRH dissatisfied groups. (A) KM curve of all-cause mortality. (B) KM curve of nonfatal MI. (C) KM curve of ischemic stroke. (D) KM curve of revascularization. (E) KM curve of cardiac death. This figure illustrates the Kaplan-Meier survival curves comparing cumulative outcomes between patients with non-ST-segment elevation myocardial infarction (NSTEMI) who reported satisfied self-rated health (SRH) and those who reported dissatisfied SRH after propensity score matching (PSM, 1:3 ratio). During the median follow-up duration of 1477 days, participants reporting dissatisfaction with self-rated health status exhibited a markedly elevated mortality risk (log-rank test, p < 0.001). The shaded areas around the curves indicate the 95% confidence intervals. Statistical test: Kaplan-Meier survival analysis with log-rank test.

  Fig. 3.. Subgroup analyses of the association between SRH and all-cause mortality. This forest plot presents the hazard ratios (HRs) and 95% confidence intervals for all-cause mortality comparing SRH dissatisfied versus SRH satisfied groups across prespecified subgroups, including sex, age (<75 or ≥75 years), and comorbidities (hypertension, DM, CKD, AF, cerebrovascular disease and chronic lung disease). Subgroup-specific estimates were derived from multivariable Cox proportional hazards regression models adjusted for age, sex, PCI, comorbidities, and in-hospital treatments. Statistical test: Multivariable Cox proportional hazards regression analysis. Symbols: Squares represent subgroup-specific hazard ratios; horizontal lines indicate 95% CIs; the dashed line denotes the overall HR. Abbreviations: HR, hazard ratio.
