  1. Statistical tests determine the significant relationship between categorical variables and OI types I, III and IV: Chi-square test or the Fisher’s exact test for contingency tables with small cell counts; Compare means of a continuous variable between OI types I, III and IV: Welch’s t-test for independent samples. As the sample size is small in each group (n < 15), results have been confirmed by Mann-Whitney U test (non-parametric test)
  2. ap < 0.05 OI type I compared to OI types III
  3. bp < 0.05 OI type III compared to OI types IV
  4. cp < 0.05 OI type IV compared to OI types I
