  • Age and BMI are presented with mean±SD. Rest of the variables are given with number and percentage (%). Age and BMI p values were obtained from Student’s t-test with unequal variances. Other variables p values were acquired from the χ2 test.

  • *Statistically significant p values (<0.05).

  • BMI, body mass index.
