Interpreting Statistical Comparisons and Procedural Changes During the TAPP Learning Curve

1

The study reported postoperative complications of 8/42, 4/42, and 2/42 across three phases, with a reported P value of .048.
2

Reconstructed Pearson tests from published counts yielded P = .105 for complications and P = .110 for mesh fixation, rather than the reported P = .048.
3

A two-sided Fisher–Freeman–Halton exact test for complications yielded P = .135, while a linear-by-linear trend test yielded P = .038.
4

Operative time decreased from 88 to 58 minutes as mesh fixation declined from 42.9% to 21.4%, so reduced fixation may have contributed to shorter procedures.
5

The correspondence does not dispute the decrease in operative time or the temporal complication pattern and seeks clarification of statistical comparisons not reproducible from published aggregate dat
