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
Sacroiliac joint (SIJ) pain is one of the most prevalent reasons for disability, it affects the contraction ratio of the muscles of the back. Imaging is critical for diagnosing back muscles. The purpose of this study was to look at changes in the muscle contraction ratio of the lumbar multifidus (LM) and erector spinae (ES) in unilateral SIJ pain. This research included 60 individuals (30 with unilateral SIJ pain and 30 healthy people (who served as matching controls). The contraction ratio of back muscles such as ES and LM was assessed using real-time ultrasonography, and the results were compared between the affected and non-affected sides in patients with unilateral SIJ pain, and healthy participants as well. In the study group, the contraction ratio of ES and LM muscles on the non-affected side was significantly higher than on the affected side (p < 0.05). as well as a significant increase in contraction ratio of the ipsilateral side (affected matched control side) LM of the healthy group compared with that of the non-affected side of the study group (p < 0.001), while there was no significant difference in contraction ratio of the contralateral (unaffected matched control side) ES of the healthy group compared with that of the non-affected side of the study group. The results of this trial demonstrate that patients with unilateral SIJ pain exhibited a substantially lower muscle contraction ratio in the ES and LM of the affected side than the non-affected side in the study group, as well as a significant increase in the contraction ratio of the ES and MF on the ipsilateral side of the control group compared with that of the study group. However, there was no significant change in the contraction ratio of the contralateral ES in healthy individuals compared to the non-affected side of the study group. The findings of the study may help in designing an appropriate exercise program to deal with patients with SIJ pain.
