Relationship between the morphology of osteophytes and cartilage lesions in anterior ankle impingement in athletes: a cross-sectional study

Table 2 Baseline characteristics of the non-protrusion and protrusion type groups

	Non-protrusion (n = 20)	Protrusion (n = 14)	P value
Sex (male/female), n	13/7	14/0	0.014*
Age, median (interquartile range)	22.0 (20.0–27.6)	27.5 (22.0–30.3)	0.148
Height (cm), mean ± S.D.	173.7 ± 10.9	176.4 ± 8.1	0.432
Body weight (kg), mean ± S.D.	73.6 ± 14.7	76.6 ± 11.2	0.535
Body mass index (kg/m²), mean ± S.D.	24.3 ± 3.6	24.5 ± 2.5	0.829
Affected side (R/L), n	12/8	7/7	0.563

Fisher’s exact test was used for sex analysis. Mann-Whitney U test was used for age. Unpaired t-test was used for height, body weight, and body mass index. Pearson’s chi-square test was used for affected side. n Number, S.D Standard deviation
*Where at significant at p < .05 for Fisher's exact test
