(a) Forest plot of observational studies exploring capillary loop width in SSc-PAH versus SSc-noPAH patients. CI: confidence interval; IV: inverse variance; MD: mean difference; REM: random effects model; SD: standard deviation; SSc-noPAH: Systemic sclerosis without pulmonary arterial hypertension; SSc-PAH: Systemic sclerosis with pulmonary arterial hypertension; WMD: weighted mean difference. (b) Sensitivity analysis including only studies utilizing right heart catheterization for SSc-PAH diagnosis; forest plot of observational studies exploring capillary loop width in SSc-PAH versus SSc-noPAH patients. CI: confidence interval; IV: inverse variance; MD: mean difference; REM: random effects model; SD: standard deviation; SSc-noPAH: Systemic sclerosis without pulmonary arterial hypertension; SSc-PAH: Systemic sclerosis with pulmonary arterial hypertension; WMD: weighted mean difference.
