Comorbidity is based on ICPC (International Classification of Primary Care) coding in the problem list in the electronic patient record.
a
Values are given as mean and standard deviation, or number (percentage).
b
In one patient in the control group, a usual blood pressure at baseline could not be found in the electronic patient file. eGFR = estimated glomerular filtration rate. Usual office blood pressure is the blood pressure as noted in the electronic patient record.
