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
Hip abductor weakness is a common functional impairment in the early postoperative phase following total hip arthroplasty (THA), often contributing to gait disturbance, pain, and delayed recovery. Emerging evidence suggests that dysfunction of the superior gluteal nerve (SGN) may play a critical role in these impairments. However, clinical evidence for SGN-targeted rehabilitation remains limited. This case series aimed to explore the feasibility and preliminary effects of physiotherapy targeting the SGN on hip abductor strength, gait speed, and walking pain in the early postoperative period after THA. Eight patients (three males and five females; aged 60-85 years) who underwent primary unilateral THA via the anterolateral approach were included. On postoperative day 14, all participants received ultrasound-guided manual therapy targeting the SGN combined with visual feedback-based therapeutic exercises for the gluteus medius and minimus. Outcome measures assessed immediately before and after the intervention included hip abductor strength measured with a handheld dynamometer, maximum gait speed measured with the 10-m walk test, and walking pain assessed with the Numerical Rating Scale (NRS). Hip abductor strength improved from 3.4 ± 0.8 kgf to 5.3 ± 1.3 kgf. Gait speed increased from 0.55 ± 0.08 m/s to 0.73 ± 0.11 m/s. NRS pain scores for walking decreased from 3.6 ± 0.6 to 1.5 ± 0.7. Ultrasound assessment revealed consistent tenderness between the gluteus medius and minimus in all participants, supporting the rationale for SGN-focused intervention. This case series demonstrated that a single session of ultrasound-guided manual therapy combined with targeted therapeutic exercise focusing on SGN function led to immediate improvements in hip abductor strength, gait speed, and walking pain in patients during the early postoperative phase after THA. These preliminary findings suggest the potential clinical value of incorporating nerve-focused interventions into standard rehabilitation programs following THA.
