Influence of referral time on patient age and sex as well as surgical versus nonsurgical management. There is a trend to significantly younger patients observed in the nonoperatively managed group A. No difference is observed in referral time between operatively and nonoperatively managed patients B, male and female patients C, nor any significant correlation between referral time and patient age at initial referral D. Spearman correlation coefficient (R) and P values are reported, with a significance level of P < .05.
