I-FABP concentrations. The relative change in plasma I-FABP (%) compared to baseline (T0 = 100%) at T1 (after walking test), T2 (after meal), and every 15 min postprandially (T3-T7). The dashed line at 150% marks a relative change of ≥50%, defined as a meaningful loss of intestinal integrity. Twelve participants showed I-FABP values ≥50% at least one time point after baseline
