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

The authors evaluated differences in the reliability of home blood pressure measurements taken in the morning, before dinner, and at bedtime. Forty-eight patients with hypertension (age range, 50-89 years; mean age, 76.4 years) measured their home blood pressure using a validated automatic information/communication technology-based device for 14 consecutive days. Those days were divided into the first seven days (1-7) and the following 8 to 14 days (days 8-14) and compared systolic blood pressure (SBP) reliability in the two periods for each measurement time point. In Bland-Altman analyses, morning SBP showed the least standard error of measurement (3.0 mm Hg). There were fixed biases in morning and before-dinner SBP with average limits of agreement of 3.9 and 6.4 mm Hg, respectively. For at-bedtime SBP, a random error was detected and the minimal detectable change was 13.8 mm Hg. The percentage of near-maximal variation of morning SBP was the smallest at 18.1%. Morning SBP therefore provided the most reliable home blood pressure value in the day.
