- TEST_HBA1C, TESTED_HBA1C, TEST_EGFR and TESTED_EGFR are auxiliary binary features indicating whether the patient had a HbA1c or a serum creatinine (from which eGFR is derived) test in this quarter, and whether the patient has ever had a HbA1c and serum creatinine test respectively. If the patient has a HbA1c or serum creatinine test in a quarter the value of their respective TEST_HBA1C or TEST_EGFR will be 1, otherwise 0. In a patient’s time-series, the value of TESTED will be 0 prior to the patient having their first HbA1c or serum creatinine test. Once the patient has had a HbA1c or serum creatinine test, the value of their respective TESTED_HbA1c or TESTED_EGFR will switch to 1 and stay at 1 for the remainder of the time-series. the statistics are the number of quarters in the entire data set where the feature contained a 1 and its relative percentage
