Statistical analysis
REGRESSION, COMPLICATIONS
Data were presented as median (interquartile range [IQR]) or as percentages. The normality of distributions was assessed using histograms and Shapiro–Wilk test. The baseline characteristics between GA and non-GA patients were compared using the The safety, procedural outcomes, and the rate of technical complications were compared with Chi-square test or adjusted Chi-square test. Logistic regression models were used to estimate the difference in safety outcomes and technical complications between the two groups. The results were estimated as risk differences, and risk ratios (RRs) with 95% confidence intervals (CIs). The subgroup analysis was performed using the SAS (version 9.4) and R (version 4.1.3) software packages. A level of
