Forest plot shows the risk ratio of masked hypertension (among clinic normotension) to white-coat hypertension (among clinic hypertension). Forest plot shows the risk ratio of masked hypertension (among clinic normotension) to white-coat hypertension (among clinic hypertension). The risk for white-coat hypertension was greater in studies that used a more strict criterion to diagnose masked hypertension (clinic systolic BP <130 mmHg, ambulatory BP ≥130 mmHg). The risk for masked hypertension was greater in studies that used a more liberal criterion to diagnose masked hypertension (clinic systolic BP <140 mmHg, home BP ≥130 to 135 mmHg).
