FABP4 and obesity due to melanocortin 4 receptor deficiency: BMI‐stratified analyses showed associations between FABP‐4 and CRC‐specific mortality (HR per SD = 1.19; 95% CI: 1.06–1.35) as well as all‐cause mortality (HR per SD = 1.16; 95% CI: 1.04–1.30) in individuals with normal BMI (<25 kg/m2), but not in those with overweight (25 to <30 kg/m2) or obesity (≥30 kg/m2) (Figure 2).
