Fixed-effects meta-analysis of apparent treatment-resistant hypertension according to additional criteria
| Analysis | Prevalence estimate (95% CI) | I2 |
|---|---|---|
| Applying a threshold of 140/90 mmHg to all patients | 0.09 (0.09 to 0.10) | 0.76 |
|
| ||
| And | ||
| Applying a threshold of 130/80 mmHg for patients with diabetes or chronic kidney disease | 0.10 (0.09 to 0.11) | 0.74 |
|
| ||
| And | ||
| Applying a threshold of 150/80 mmHg for patients >80 years regardless of morbidity | 0.09 (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.
