  1. Measures of prevalence (score 1-5) and severity (score 3-5) of osteochondrosis (OC) and prevalence of osteochondrosis dissecans (OCD), synovitis, and any lesion (OC and all other lesions in the joint). Significant (Sign.) differences between groups and sex are indicated by asterisks *p???0.05; **p???0.01; ***p???0.001; n.s.; non-significant. ^Only the difference in prevalence of OC was examined, as no cases of OC score 4-5 were recorded.
