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.
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
backgroundAikido is a martial art comprises of locking techniques and falls. During the locking techniques, the elbow joint is forced into extended position. Moreover, the elbow hits the ground during the falling techniques. These might compromise joint position sense (JPS). The objectives of this study were to compare JPS and strength of the muscles of elbow joint between Aikidokas and a non-athlete group and to evaluate the correlation between JPS and muscle strength among Aikidokas.
methodsAll male Jiyushinkai style Aikidokas and a healthy matched non-athlete group participated in this cross-sectional study. Passive JPS at a speed of 4°/s and the isokinetic strength of elbow flexors and extensors were assessed.
resultsEvaluating the isokinetic parameters revealed no significantly difference between the groups in either flexion or extension at speeds of 60 (P-value range: 0.2-0.99) and 120 °/s (P-value range: 0.05-0.96). Also, the groups had no significant difference regarding different types of reconstruction error including constant error (P-value range: 0.38-0.91), variable error (P-value range: 0.09-0.87), and total variability (P-value range: 0.30-0.80). Moreover, very weak to weak correlation was observed between isokinetic parameters and passive JPS (r-value range: 0.01-0.39).
conclusionsJPS was not impaired in Aikidokas in spite of the repetitive stress applied to the elbow joint during the performance of Aikido techniques. The lack of significant difference in isokinetic between Aikidokas and healthy non-athletes, and the absence of an acceptable correlation between IPS and muscle strength in Aikidokas, might be attributed to the soft nature of Aikido.
