Statistical methods
trismus, swelling, pain
TRISMUS
The database was built in the IBM SPSS® software version 20.0 platform (IBM Corp., Armonk, NY, USA). Descriptive and inferential statistical analyses were performed. The descriptive data analysis was presented as absolute and relative frequencies and means. The Kolmogorov-Smirnov test was used to test the normality of the quantitative variables for the inferential statistics. The t-test for paired samples was used to compare the means of quantitative variables (swelling and trismus), while the Wilcoxon Signed Rank test was used to assess differences in ordinal variables (pain and Landry index) between the intervention groups (primary vs. partial suturing of the relieving incision). A significance level of 5% (p < 0.05) was adopted for all statistical tests.
