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
Iatrogenic femoroacetabular impingement following periacetabular osteotomy (PAO) is a well-documented cause of postoperative complications. The anterior inferior iliac spine (AIIS) is an increasingly recognized source of impingement, and previous studies have documented high rates of abnormal AIIS subtypes in dysplastic hips undergoing PAO. This study evaluates the effects of PAO with concomitant AIIS osteoplasty on a range of motion and function. We performed a retrospective study of 63 hips that underwent PAO with concomitant open AIIS osteoplasty. AIIS was classified using 3D-reconstruction Computed tomography (CT) and femoral version was measured on axial-CT. Pre- and post.-operative lateral center-edge angle, Tönnis-angle, and anterior center-edge angle were calculated using X-ray imaging. Hip internal rotation (IR) at 90° flexion was recorded preoperatively, intraoperatively following PAO (pre- and postosteoplasty), and 6 months postoperatively. Pre- and postoperative Merle-d'Aubigné (MDA) scores were compared using pairwise
