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 aim of the current study was to perform a systematic review and meta-analysis to evaluate the relationship between step count and changes in blood pressure (BP). Studies involving healthy adults and an intervention in the form of brisk walking with a pedometer were included. Net changes in BP and step count in each trial were calculated and pooled. In addition, the pooled net changes of two categories (trials that achieved walking 10,000 steps a day and those that did not) were compared. A meta-regression analysis was performed to examine the relationship between net changes in BP and step count. Fourteen trials were analyzed. Pooled net changes in BP improved significantly (systolic BP, -3.1 mm Hg; diastolic BP, -1.6 mm Hg). When the trials were categorized depending on whether they achieved walking 10,000 steps a day, the pooled net change in systolic BP and diastolic BP did not differ significantly between both groups of subjects. The meta-regression analyses indicated that net change in systolic BP was significantly associated with an increased step count (e.g., systolic BP is expected to decrease approximately 4 mm Hg if increased step count by 2000 steps a day). However, net change in systolic BP was not associated with the step count in an intervention group following the intervention. At present, there is presumably no evidence that walking 10,000 steps a day lowers the BP to any marked degree. In order to reduce systolic BP by walking with a pedometer, one should be mindful of increasing one's step count.
