BMI = body mass index; HbA1c = hemoglobin A1c.

^aMean and percentiles are calculated for patients with at least one record of the specified type.

^bThere is not complete correspondence between systolic and diastolic blood pressure measurements. However, the statistics displayed here match for both systolic and diastolic measurements. Of the 28,178,774 blood pressure records, 14,148,706 (50.2%) are diastolic and 14,030,068 (49.8%) are systolic.

^cThere are fewer patients with at least one systolic blood pressure measurement, 1,165,562.

^dOther labs include laboratory measurements of blood, serum, and urine, including blood cell counts, blood chemistry, and markers of liver and kidney function such as alanine aminotransferase, aspartate aminotransferase, and estimated glomerular filtration rate, and numerous other measurements.

^eMedications of special interest include antidiabetics, lipid lowering medications, and antihypertensive medications.

^fThe top fifteen other medications are ibuprofen 800 mg, omeprazole 40 mg, fluticasone propionate 0.05 mg, azithromycin 250 mg, ibuprofen 600 mg, zolpidem tartrate 5 mg, omeprazole 20 mg, naproxen 500 mg, gabapentin, prednisone 20 mg, oxycodone hcl, levothyroxine sodium, ondansetron 4 mg, aspirin 500 mg, acetaminophen 500 mg/hydrocodone bitartrate 5 mg. Each represents <1% of all records.

^gProcedures are medical procedures such as ultrasounds and colonoscopies.
