near-significantP = .082
Our exploratory analysis revealed a near-significant inverse correlation between BMI and SC infliximab trough levels ( P = .082), and a stepwise decrease in median trough levels across BMI categories was observed: 29.0 (20.0, 45.0) mcg/mL in normal weight patients, 23.0 (10.4, 40.0) mcg/mL in overweight patients, and 20.0 (12.0, 39.0) mcg/mL in obese patients, though this did not reach statistical significance.
