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
objectivesThe effect of three-dimensional (3D) printed bone-attached guide plate assisted cannulated screw fixation of pelvic fracture is reliable, but extensive soft tissue dissection is still required when installing the guide plate. This study aims to compare the efficacy of posterior pelvic ring fracture fixation with iliosacral screw insertion between the assistance of modified percutaneous patient specific 3D printed guide template and conventional fluoroscopy.
methodsFrom May, 2019 and September 2021, 28 patients sustained posterior pelvic ring fractures were randomized into 2 groups: A guide template group, in which the iliosacral screw was inserted for fixation of the posterior pelvic ring fracture with the assistance of modified percutaneous patient specific 3D printed guide template, and a fluoroscopy group, in which the iliosacral screw was inserted under the guidance of conventional fluoroscopy. The operation time, fluoroscopic frequency, intraoperative blood loss, and incision length were recorded for each screw insertion. Fracture reduction was evaluated according to the Matta criteria. The screw position was evaluated according to the modified Gras classification, and the functional outcome was evaluated according to Majeed score. The parameters of both groups were compared, and statistical analysis was performed.
resultsAll the 28 patients were followed up for 12-24 months. Of them, 15 iliosacral screws were inserted in 14 patients in the guide template group, and 14 iliosacral screws were inserted in 14 patients in the fluoroscopy group. The operation time, fluoroscopic frequency, screw deviation, incision length, and blood loss in the guide template group were 20-30(25.8±2.8) min, 9-15(12.2±1.9), 2-4(2.6±0.7) mm, 4-5(4.6±0.5) cm, and 5-10 (7.8±1.7) mL, respectively, whereas those in the fluoroscopy group were 30-60(48.1±7.5) min, 40-96(64.7±16.3), 3-6(4.2±0.9) mm, 0.8-1.2(1.0±0.1) cm, and 2-5(3.1±1.3) mL, respectively, and there were statistical significance (all
conclusionsCompared with the conventional fluoroscopy, it would cost less operation time, less fluoroscopic frequency and increase more accurate screw insertion to fixate the posterior pelvic ring fracture with the assistance of modified percutaneous patient specific 3D printed guide template.
