Fourth, the borderline significance ( P = 0.044) with confidence interval approaching unity (OR = 1.51, 95% CI: 1.01–2.24) suggests our finding is hypothesis-generating rather than definitive.

Although the interaction term did not reach statistical significance (P for interaction = 0.067), this trend likely reflects limited statistical power within subgroups, particularly given the small sample size in the minimally invasive PH cohort ( n = 20) [ 34 ].
