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
purposeFragility fractures of the pelvis (FFPs) are increasingly common owing to aging populations of several countries and the increasing osteoporosis incidence. Surgical interventions, including percutaneous screw fixation, are performed to avoid complications associated with prolonged bed rest for FFP management. However, conventional fluoroscopy for surgical navigation is difficult owing to issues such as insufficient tissue imaging, difficulty achieving accurate screw placement, and high radiation exposure to surgeons. This study aimed to compare the effectiveness of the O-arm-based navigation system with that of conventional fluoroscopy for percutaneous screw fixation in patients with FFPs, focusing on surgical outcomes, radiation exposure, and screw-placement accuracy.
methodsThis retrospective multicenter study was conducted between April 2020 and May 2024. Seventy-two patients with FFPs were divided into two groups: O-arm (O, n = 14) and the conventional fluoroscopy (C, n = 58) groups. Primary evaluation parameters were radiation exposure and screw-placement accuracy. Demographic and surgical data, including surgery duration and intraoperative blood loss, were collected for secondary evaluation.
resultsThere was no significant differences in demographic data between groups. Surgeon radiation exposure was lower in the O group (0.1-0.2 µSv) than in the C group (mean exposure: 109.8 ± 61.3 mGy). The screw-perforation rate was lower in the O group (5.7%) than in the C group (20%). No patients in the O group required reoperation; however, three patients in the C group did.
conclusionCompared with conventional fluoroscopy, the O-arm-based navigation system improves screw-placement accuracy and significantly reduces surgeon radiation exposure.
