But the secretary of state's report notes flaws in the audit logs that will be harder to erase: wrongly recorded entry dates and times, and silent deletions of audit logs.
In 2001, Montano moved to the United States, having lied to immigration authorities about his military record and entry date to obtain work papers.
When patients had new onset of multiple symptoms recorded, the entry date was the earliest recorded date of the new symptom in the study period.
We restricted all values of these variables to those that had been recorded in the person's electronic healthcare record before baseline, except for BMI and alcohol and smoking status for which we used the values recorded closest to study entry date and recorded before the diagnosis of osteoporotic fracture (or before censoring for those who did not develop a fracture).
Children with CD recorded before their entry date were considered to have prevalent disease and were thus excluded.
Patients will be subdivided into two groups evaluated on the date when they started taking statins: those without CVD records before the entry date (taking statins for primary prevention); those with CVD diagnosed at or before entering the study (taking statins for secondary prevention).
The most recent smoking status record by the study entry date defined smoking status at baseline when available; if not recorded, the first subsequent record defined smoking status at baseline.
We restricted all values of these variables to those recorded in the person's electronic healthcare record before baseline, except for ethnicity, smoking status, systolic blood pressure, total serum cholesterol:HDL cholesterol ratio, and body mass index, where we used the values recorded closest to the study entry date and recorded before the patient had the outcome or was censored.
The following variables were also retrieved from the database using the latest record prior to cohort entry date: age, gender, smoking status, body mass index (BMI; or imputed BMI using the latest height and weight measurements where BMI data were not recorded), Medical Research Council (MRC) dyspnoea grade and FEV1percentt predicted.
For each of the continuous clinical variables, we used the value recorded closest to the baseline cohort entry date out of all those recorded before the baseline date or within the six months after this date.
For body mass index and smoking status, we used the values recorded closest to the study entry date.
