Meta-Analysis: Prevalence and Incidence of Gastroparesis Following Lung or Heart Transplantation.

3.2.1 Subgroup Analysis by Transplant Type Subgroup analysis by transplant type demonstrated a higher prevalence among HLT recipients (44.89%, 95% CI: 17.05–76.35; prediction interval: 0.71–98.94) compared with LT alone (26.95%, 95% CI: 15.46–42.68; prediction interval: 2.08–86.49); however, this difference did not reach statistical significance ( p = 0.31) (Figure 3A ). 3.2.2 Subgroup Analysis by Diagnostic Modality When stratified by gastroparesis diagnostic modality, the highest prevalence was observed with standardized 4‐h (GES) (42.44%, 95% CI: 22.70–64.92; prediction interval: 2.52–95.46), followed by T 1⁄2‐based scintigraphic testing (37.13%, 95% CI: 22.84–54.10; prediction interval: 6.31–83.82), and clinical or non‐scintigraphic diagnosis (13.15%, 95% CI: 2.89–43.52; prediction interval: 0.06–97.51).
