Pearson chi‐square test was used to compare age groups in terms of duration of symptoms. The duration of symptoms marked with (a) made significant contributions to the chi‐square statistic as determined by the adjusted residual scores.
Pearson chi‐square test was used to compare age groups in terms of metabolic status at presentation. The metabolic status at presentation marked with (b) made significant contributions to the chi‐square statistic as determined by the adjusted residual scores.
Pearson chi‐square test was used to compare age groups in terms of severity of DKA. The severity of DKA marked with (c) made significant contributions to the chi‐square statistic as determined by the adjusted residual scores.
Abbreviation: DKA, diabetic ketoacidosis.
