Discussion We hypothesized that diabetes, smoking, and BMI ≥30 would be significant risk factors for nonunion; in adjusted analyses, idiopathic peripheral neuropathy and bilateral surgeries were significant predictors, BMI ≥30 showed a trend, and diabetes/smoking were not identified as significant factors.

The sentences
Per-patient models identified idiopathic peripheral neuropathy and bilateral surgeries as independent predictors, with BMI ≥30 showing a trend toward significance.
Within our study, peripheral neuropathy was associated with increased risk of nonunion (OR 5.875, 95% CI 1.955-17.655); however, it did not reach statistical significance.
