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

objectivesThis study aimed to examine the morphological characteristics and stiffness of the bilateral Achilles tendon (AT) and jump performance, as well as to investigate the relationship between these factors in male and female university Kendo athletes.

methodsTen male and ten female trained university Kendo players participated in the study. Magnetic resonance imaging was used to capture images of the sagittal and transverse images of the AT, from which the transverse cross-sectional area (CSA), length, and volume were calculated. AT stiffness was also assessed using the MyotonPRO, and rebound jump and single-leg hop performance were measured.

resultsThe maximum CSA of the AT was significantly greater in the left leg than in the right leg (p<0.05). No significant relationship was found between AT characteristics and jumping performance, regardless of gender or whether the left or right leg was considered.

conclusionsThese results suggest that the characteristic kinematic loading of the left leg during jumping in Kendo may lead to different adaptations in AT morphology between the left and right legs, regardless of gender.
