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

In fourteen subjects we compared maximum voluntary eccentric, concentric, and isometric contractions. The maximum voluntary forces by the subjects on a weight-lifting rod when changing from standing to squatting and from squatting to standing, and during a halfway knee-bend, were measured. The rod was placed on a special stand and moved up and down at a constant speed of 8.5 m/s by a motor. Energy expenditure was measured by the indirect method and EMG activity was measured in the quadriceps femoris. It was found that the force which the muscles generated was greatest during eccentric contraction, lower during isometric and lowest during concentric contraction. Energy expenditure was slightly greater during concentric than eccentric contraction. The level of difference in EMG activity of the quadriceps femoris was statistically insignificant. An energy comparison with isometric contractions was not undertaken in view of the very complex nature of these relationships.
