And
Applying a threshold of 130/80 mmHg for patients with diabetes or chronic kidney disease0.10 (0.09 to 0.11)0.74
And
Applying a threshold of 150/80 mmHg for patients >80 years regardless of morbidity0.09 (0.08 to 0.10)0.76
And
Applying a threshold of adequate dosing in all medications (WHO-DDD)0.04 (0.04 to 0.05)0.83
And
Applying a threshold of adequate adherence (>75% prescriptions)0.03 (0.03 to 0.04)0.80
  • CI = confidence interval. WHO-DDD = World Health Organization-defined daily dosing. I2 is the percentage of variance in the meta-analysis that is attributable to study heterogeneity.
