Table 1. Comparisons of Sample Size and Shapiro-Wilk Goodness-of-fit P Values for Log-normal Distribution

Tabular comparisons of sample size and Shapiro-Wilk goodness-of-fit P  values for the log-normal distribution for TT and ST. 6,052 CPT1–2 combinations were not fit due to insufficient sample size (n ≤ 4). Values shown are number of surgeries, and the percent of the total row appears in parentheses; n = 3,266 surgeries, 260 fit CPT1–2 combinations.

CPT = Common Procedural Terminology code; ln = the natural logarithm; NF = not fitted; ST = surgical time; TT = total time.
