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
This study compares the changes in pathway and center of gravity (COG) on the calcaneus of non-involved and involved sides according to eccentric and concentric strengthening in patients with unilateral Achilles tendinopathy. The goal was to define the biomechanical changes according to eccentric strengthening for the development of clinical guidelines. Eighteen patients with Achilles tendinopathy were recruited at the K Rehabilitation Hospital in Seoul. The subjects were instructed to perform 5 sessions of concentric strengthening. The calcaneal pathway was measured using a three-dimensional (3D) motion analyzer, and COG was measured by a force plate. Subsequently, eccentric strengthening was implemented, and identical variables were measured. Concentric and eccentric strengthening was carried out on both the involved and non-involved sides. There was no significant difference in the calcaneal pathway in patients with Achilles tendinopathy during concentric and eccentric strengthening. However, during eccentric strengthening, the calcaneal pathway significantly increased on the involved side compared to the non-involved side for all variables excluding the z-axis. COG significantly decreased on the involved side when compared to the non-involved side in patients with Achilles tendinopathy during eccentric and concentric strengthening. During concentric strengthening, all variables of the COG significantly increased on the involved side compared to the non-involved side. Compared with eccentric strengthening, concentric strengthening decreased the stability of ankle joints and increased the movement distance of the calcaneus in patients with Achilles tendinopathy. Furthermore, eccentric strengthening was verified to be an effective exercise method for prevention of Achilles tendinopathy through the reduction of forward and backward path length of foot pressure. The regular application of eccentric strengthening was found to be effective in the secondary prevention of Achilles tendinopathy in a clinical setting.
