Statistical Analysis

Statistical analyses were performed with IBM SPSS Statistics, version 27.0 (IBM Corp., Armonk, NY). Tests were conducted 2-tailed and an alpha level of 0.05 defined statistical significance. Power analysis confirmed the sample size was adequate based on a medium effect size, a power of 0.80, and an alpha level of 0.05. Patient characteristics are expressed as frequencies (percentage) for categorical variables and median (interquartile range) for continuous variables. Normality was assessed by the Shapiro–Wilk test (P > .05). A Mann–Whitney U test was conducted to determine significant differences in patient characteristics and graft sizes. The χ² test or Fisher exact test was conducted to determine significant differences in categorical patient characteristics and need for augmentation. To adjust for confounders, logistic regression was conducted to determine the association between the 2 procedures and the need for augmentation. Linearity was assessed by the Box–Tidwell procedure. Multicollinearity was absent.
