*Cleft type, which is classified according to ICD9 diagnostic codes [32], as well as sex ratios, unilateral to bilateral and left to right ratios were calculated using a denominator of the 35,323 patients with complete, valid entries recorded.
**The total number of patients with a recorded cleft type is 35,323.
