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
purposeSpinopelvic fixation surgery is widely used for adult spinal deformity, but its impact on hip joint pathology remains unclear. This study investigates its association with femoroacetabular impingement syndrome (FAIS) using ultrasonography.
methodsThis retrospective study included 80 patients (160 hips) who underwent spinal fusion for adult spinal deformity. Patients were categorized based on sacroiliac joint fixation into fixation (group F) and non-fixation (group N). Ultrasonography was performed to assess hip morphology, including labral degeneration, cam lesions, and acetabular osteophytes. The Kellgren-Lawrence (KL) grade, and alpha angle were measured on standing radiographs. The anterior impingement test was conducted to evaluate clinical symptoms, and prevalence was statistically compared.
resultsWe analyzed 151 hips (26 males, 125 females) with a mean follow-up of 52.7 ± 39.6 months. After excluding 27 hips with advanced hip osteoarthritis (KL grade ≥ 2), labral degeneration (69.5% vs. 37.9%, p = 0.0076) and cam lesions (30.5% vs. 6.9%, p = 0.01) were significantly more prevalent in group F than group N. The mean alpha angle did not significantly differ between two groups at the time of surgery, but significantly greater in group F compared to group N (48.7 ± 3.9° vs. 46.7 ± 4.7°, p = 0.01) at final follow-up.
conclusionSpinopelvic fixation may contribute to FAIS-related hip abnormalities by increasing mechanical stress. Ultrasonography may aid in early detection of hip joint changes after adult spinal deformity surgery.
