1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Home blood pressure monitoring (HBPM) is essential for long-term hypertension management, but its accuracy and reliability is questionable due to user inconsistencies and non-standard usage conditions. This study compared two validated HBPM devices - a wrist-based and a reference upper-arm monitor - in a home-like setup where participants placed the devices themselves. A total of 121 participants underwent four concurrent blood pressure (BP) measurements, with two taken in each arm, followed by a crossover of devices between arms after the initial two readings. Wrist-derived BP readings were higher than upper-arm measurements. With higher blood pressure levels, both devices exhibited greater bias, accompanied by reduced precision in systolic BP measurements. Additionally, hypertension classification showed only moderate agreement (Cohen's kappa=0.58). The wrist monitor tended to over-diagnose hypertension and exhibited greater variability than the upper-arm device. These findings highlight the need for more guidance and education as well as critical evaluation of home blood pressure measurements provided by patients.
