Adjusted for time from trauma to inclusion and baseline return to sports. Missing values ranged up to 1.6%. NPRS, numeric pain rating scale on a scale from 0 to 10, with a higher score indicating more pain.
MR: magnetic resonance; 95%CI: 95% confidence interval; OR: odds ratio; AUC: area under the curve.
