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

Marfan syndrome (MFS) is a connective tissue disorder caused by structural changes in fibrillin-1 and is associated with muscle weakness and joint pain. The understanding of lower extremity (LE) joint mechanics associated with joint pain in people with MFS is limited. The goal of this study was to assess LE joint mechanics during the sit-to-stand (STS) task in people with MFS compared with asymptomatic controls. Sixteen people with MFS and 16 sex- and body mass index-matched controls were tested in this study. All participants performed the STS task at a self-selected speed. Peak LE joint extensor moments, moment impulses, moment durations, time to task completion, total support moment (TSM), and each joint's contribution to the TSM were evaluated. People with MFS took longer to perform the task and exhibited lower peak knee extensor moments and higher peak ankle plantar flexor moments compared with controls. Higher LE joint extensor moments impulses and moment durations were observed in people with MFS. People with MFS performed the STS task using a higher TSM with higher ankle contributions to the TSM. People with MFS exhibit altered LE joint mechanics during the STS task and utilize a more ankle joint dominant strategy.
