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

Slips and falls from ladders are a common cause of workplace injuries, yet insufficient research explains the cause of these incidents. This study identifies the association between the required coefficient of friction (RCOF) and biomechanical factors (foot angle, body angle, foot-body coupling angle, foot contact velocity, foot placement, and trunk center of mass velocity) during ladder descent. In bivariate regression analyses with the ladder angle as a covariate, foot angle was negatively associated with RCOF (i.e. toe-down has a higher RCOF) (t
