The influence of obesity and gender on outcome after reversed L-shaped osteotomy for hallux valgus

Table 2 Logistic regression model for particular factors associated with radiological relapse of hallux valgus deformity (HV) (HV angle [HVA] > 15°) and BMI as well as gender after reversed L-shaped osteotomy (ReveL) for HV (n = 799)

Main effect of variable	Category	Adjusted OR (95% CI)^a	P-value^b
BMI (kg/m²)
	< 30.0	1.00 (reference)
	≥30.0	1.10 (0.70–1.75)	0.675‡
Gender
	Female	1.00 (reference)
	Male	1.91 (1.19–3.06)	0.007

Abbreviations: OR Odds ratio, % percent, CI Confidence interval, BMI Body mass index, kg kilograms, m metres
^aAdjusted for confounders and effect modifiers: age, gender, preoperative hallux valgus angle, number of screws, additional surgical technique for hallux valgus, time period, and body mass index
^bWald test
^‡The p-value remained insignificant if the BMI category was set to < 25.0 versus ≥25.0 (adjusted OR = 1.04 [95% CI 0.74–1.48], p = 0.817)
