Comparison of incision parameters (L, D1, Α, and D2) between younger and older groups

Variables	Younger Group (n = 67)	Older Group (n = 37)		t/U	p value
L(mm)	40.04 ± 6.65	40.68 ± 8.82	0.130		0.897
D1(mm)	38.75 (11.26)	34.29 (13.45)	1699.0		0.002
α(°)	144.15 (19.37)	135.24 (19.55)	1675.5		0.003
D2(mm)	5.15 (9.15)	2.45 (5.72)	1521.0		0.025

Note:Continuous variables are presented as Mean ± SD for normally distributed data or Median (IQR) for non-normally distributed data. Normality was assessed using the Shapiro-Wilk test. For normally distributed variables, an independent-samples t-test was used to compare means between groups. For non-normally distributed variables, the Mann-Whitney U test was used. Statistical significance is indicated by p < 0.05
