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

Nocturnal blood pressure (BP) dipping is a risk factor for cardiovascular disease, independent of nighttime BP levels. We compared nocturnal BP dipping detected by conventional ambulatory BP monitoring (ABPM) with that detected by nocturnal home BP monitoring (HBPM), which can measure BP during sleep with a timer function. We analyzed data of 927 subjects in the nationwide practice-based J-HOP Nocturnal BP Study and observed that the prevalences of nocturnal BP dipping status for HBPM and ABPM respectively were: extreme dipper, 6.9% and 14.8%; dipper, 36.1% and 42.4%; non-dipper, 42.8% and 33.2%; riser pattern, 14.1%, and 9.6%. The agreement between nocturnal dipping classification by HBPM and ABPM was 41.0%, and when we used ≥3 days of HBPM data, the agreement rate increased to 42.8%. Obtaining an increased number of nighttime BP measurements at home for multiple days may increase the reliability of assessments of nocturnal BP dipping status detected by HBPM.
