Figure 4. Crude and adjusted hazard ratio with corresponding 95% CIs for 3 fQRS strata (non‐fQRS as the reference) on hospitalization for heart failure, cardiovascular mortality, all‐cause mortality, and composite end point.

The multivariate model was adjusted for age, sex, body mass index, hypertension, diabetes, heart failure, hyperlipidemia, cardiovascular disease, estimated glomerular filtration rate, and left ventricular ejection fraction. fQRS indicates fragmented QRS.
