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

aimTo date no age-comparative study has been reported about effect of exercise on muscle pump action change, while its effect is suggested to differ in ages. This study aims to clarify the changes in muscle pump action with aging by measuring the muscle and vein area, and blood flow in lower legs.

methodsSubjects were healthy volunteers and consisted of three groups: young age group (N = 20), middle age group (N = 20) and old age group (N = 16). The lower leg flexor muscle area and popliteal vein area were measured by using T1-weighed magnetic resonance imaging at the condition pre- and post-ankle exercise in three positions. Moreover, popliteal blood flow velocity was also measured using phase contrast magnetic resonance imaging.

resultsThe elderly had the highest number of individuals who had exercise habits (p < .001). In a multiple linear regression analysis, sitting posture, leg muscle volume, and rate of change in the soleus muscle were significantly related to blood flow velocity change.

conclusionsNo difference was found in the changes in muscle pump action with age. The study results suggested that elderly people with exercise habits might be able to maintain the muscle pump action.
