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

Hamstring strain injuries (HSI) are common in field-based sports. Musculoskeletal modeling studies have been used to investigate hamstring mechanics during steady-state running. Accelerative and decelerative running as well as change of direction actions, which are common mechanisms of HSI, have been largely overlooked. Therefore, the aim of the present study was to investigate the mechanics of the biarticular hamstrings during acceleration, deceleration, and sidestep cutting tasks. Three-dimensional motion analysis, ground reaction force and electromyography data were collected for 20 recreationally active adults performing acceleration, deceleration and 45-degree sidestep cutting. Musculoskeletal modeling was used to solve for musculotendinous (MTU) force, stretch, and work. Peak MTU force occurred during acceleration for biceps femoris long head (1.5 body weights (BW)) and semimembranosus (2.7 BW), whereas it occurred during deceleration for semitendinosus (0.7 BW). Peak stretch was highest in deceleration for all hamstrings (10.9% to 13.7%), followed by sidestep cutting (8.9% to 12.4%) then acceleration (5.5% to 10.2%). The greatest negative work performed by biceps femoris long head occurred during acceleration and sidestep cutting (-0.25 J·kg
