Statistical Analysis
The R language was used to analyse the data.11,12Numerical data was analysed with the Shapiro-Wilk test for normality distribution. The unpaired Two Sample T-test (w), reported as mean ± standard deviation, or Mann-Whitney U-test (u), reported as median [Interquartile Range (IQR)], was used depending on distribution. Categorical data were analysed with Chi-squared test (x2) or Fisher’s Exact Test (f). Odds ratio (OR) was calculated to determine the degree of association between the type of procedure and analgesia requirement. Sub-analysis based on the aim of the procedure were also performed and analysed with the Kruskal Wallis test. Significance value was set at p ≤ 0.05.
