  "description": "In the Clinical Practice Research Datalink (CPRD, primary care data) we extracted Low Density Liporotein (LDL) measurements using the structured data component of the test CPRD table (entity type 177 and 288) combined with the Read terms below.\n\n\nMeasurements were extracted from the data2 field and units from the data3 field. We extracted all values recorded in mmol/L (SUM lookup 96) or mg/dL (SUM lookup 82) and filtered out values below 0 or above 50 mmol/L. Where multiple measurements were present in a single consultation (identified by the consid identifier) we calculated the average.\n\n\n\n\n",
