Details of groups from which bone was removed
| Group | No. of patients | Sex(M/F) | Median age(oldest, youngest) |
|---|---|---|---|
| Analysis of sex matching was performed using a χ2 test. Age distributions were analysed using one way analysis of variance followed by Tukey’s test for pairwise comparisons, when normally distributed, or Kruskal-Wallis one way analysis of variance on ranks if data failed the Kolmogorov-Smirnov test for normality with p<0.05 (p>0.05 indicates no significant differences between groups). *†Pairs of variables that are significantly different (p<0.05). | |||
