values for the Anderson-Darling normality test are as follows: (1) time to sensory block: AX, ; IC, ; SC, ; (2) duration of analgesia: AX, ; IC, ; SC, . Continuous variables are reported as median [interquartile range], and comparisons are analyzed by one-way ANOVA and subsequent Tukey’s HSD test. For categorical variables, comparisons are analyzed by two-tailed Fisher’s test. Additional Fisher’s tests are as follows: (3) success rate: AX = IC, ; IC = SC, ; (4) late dysesthesia: AX = IC, ; AX = SC, ; IC = SC, . AX, axillary; IC, infraclavicular; SC, supraclavicular; n, numbers; n/a, not applicable; NS, not significant (). |
