BP: blood pressure; DBP: diastolic blood pressure; SBP: systolic blood pressure; HCTZ: hydrochlorothiazide; HTN: hypertension. Negative impact is denoted by a minus (−) sign: increases BP levels and decreases odds of BP control. Positive impact is denoted by a plus (+) sign: decreases BP levels and increases odds of BP control.
