  1. Coef: coefficient value (ranges from − 1 to 1 and indicates that a change of 1 unit in the variable will result in a change of x units in the outcome score). Only p values below 0.05 are reported
  2. “–” indicates no statistical significance. Adjusted for age, sex, body mass index, and AO fracture classification
