  1. eICW, distance between mild palate plane and the centre of dento-gingival junctions of primary canine; eIMW, distance between mild palate plane and the centre of dento-gingival junctions of first molar; CBS, cross-bite side; nCBS, non cross-bite side
  2. *P values based on Independent Student’ t test for intra-timing side-to-side measurements and set at p < 0.05
  3. **P values based on paired Student’ t test for inter-timing mean differences and set at p < 0.05; NS, non significant
  4. ***P values based on Independent Student’ t test for inter-groups comparison of the mean of differences and set at p < 0.05
