Adjusted differences in KOOS and VAS scores at the last follow-up in patients with different characteristics.

	Change vs. Reference	p Value	Model Covariates
KOOS
Thyroid disease	−14.4 ± 4.9	p = 0.003	Diabetes, KOOS at baseline
Diabetes	−12.5 ± 6.7	p = 0.064	Thyroid disease, KOOS at baseline
KL grade 4	−21.05 ± 10.3	p = 0.043	KOOS at baseline
Previous ACL reconstruction	+10.0 ± 4.0	p = 0.013	KOOS at baseline
VAS
Previous PRP injections	−1.83 ± 0.70	p = 0.010	VAS at baseline, follow-up time

Adjusted changes were calculated using linear model selected for Bayesian information criteria (BIC) minimization. Several models were tested for the following categories of variables: demographics, comorbidities, previous intervention, and diagnosis. Reference is represented by mean of patients who did not present the specific condition.
