PY - 2020 DA - 2020/02/24 TI - Development and validation of algorithms to classify type 1 and 2 diabetes according to age at diagnosis using electronic health records JO - BMC Medical Research Methodology SP - 35 VL - 20 IS - 1 AB - Validated algorithms to classify type 1 and 2 diabetes (T1D, T2D) are mostly limited to white pediatric populations. We conducted a large study in Hong Kong among children and adults with diabetes to develop and validate algorithms using electronic health records (EHRs) to classify diabetes type against clinical assessment as the reference standard, and to evaluate performance by age at diagnosis.
