  • Numbers indicate their ranking in terms of discriminatory ability within studies, with 1 representing the most discriminatory. # indicates used as part of an algorithm, but discriminatory value of individual criteria not reported. × indicates features not discriminatory. ‘Inc’ indicates inclusion criteria for the study, so feature could not be used to discriminate. Only features reported in more than one paper shown (see text for details of others).

  • BMI, body mass index; DKA, diabetic ketoacidosis.
