Height, weight, and BMI data are converted into a mean with standard deviation score, other data are presented as mean with standard deviation or number of patients (%).

DM = diabetes mellitus, BMI = body mass index, DKA = diabetic ketoacidosis, HbA1c = glycosylated hemoglobin, BUN = blood urea nitrogen, eGFR = estimated glomerular filtration rate, SGA = small for gestational age, FHx = family history.

The items marked with small alphabet letters represent the total number of items, which are as follows:

Type 1 DM: aBMI (n =91), bSexual maturity rate (n = 74), cDuration since onset (n = 91), dWeight loss (n = 90), eKetonemia or ketonuria (n = 92), fpH/Bicarbonate (n = 91), hCorrected Na (n = 91), iAnion gap (n = 91), kTotal CO2 (n = 68), lInsulin (n = 80), mC-peptide (serum) (n = 90), nC-peptide (24-hr urine) (n = 65), oKetone (urine) (n = 91), pKetone (serum) (n = 75), rSGA (n = 84), sFHx (n = 86).
