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
backgroundThis study aimed to investigate the effects of neuromuscular electrical stimulation (NMES) of gluteus medius on hip function and sleep quality in patients with sleep disorders after hip arthroplasty (HA).
methodsThis retrospective analysis included 100 patients who underwent HA between January 2022 and August 2025 and developed postoperative sleep disorders. Patients were divided into in a control group (n = 45) and an NMES group (n = 55) based on the treatment received. The NMES group received NMES applied to the gluteus medius; both groups were treated for 4 weeks. Patient data extracted from the medical record system included hip function scores and sleep records: visual analogue scale (VAS), Harris Hip score, Berg Balance Scale (Berg) score, and Pittsburgh Sleep Quality Index (PSQI) score. These measures were compared between the two groups before and after treatment. Therefore, the correlation between VAS score and PSQI score was analysed.
resultsAfter treatment, hip function and sleep quality improved in both groups. VAS scores decreased significantly after 4 weeks of treatment in both groups (p < 0.05), with the NMES group showing lower scores than the control group (p < 0.05), Harris and Berg scores increased significantly in both groups(p < 0.05), and both were higher in the NMES group (p < 0.05). The PSQI score in the NMES group was lower than that in the control group (p < 0.05). Correlation analysis showed a strongly positively correlated between VAS and PSQI scores in both groups before treatment (p < 0.05); after treatment, a weak positive correlation remained in the NMES group, whereas a moderate positive correlation persisted in the control group.
conclusionsApplying NMES to the gluteus medius is associated with reduced pain intensity in patients with sleep disorders after HA. This may contribute to improved sleep quality and help alleviate the reciprocal interaction between pain and sleep disorders.
