Effect of Iliosacral Screw Implantation Through a New Channel in Three-Dimensional Printing Pelvic Model.
Article in Indian journal of orthopaedics, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe exit point of classic iliosacral screw (ISS) is deep and viewing device cannot be used, implantation of ISS may lead to malposition and nerve injury.
objectiveThe aim of this study is to explore the effect of ISS implanted through a new channel (NSIS) with the aid of a viewing device.
methodsWith the aid of a viewing device, NISSs were implanted into 50 3D printed pelvis models (1:1), in which the entry point was located at a vertical distance of 6 mm from the middle of the superior posterior quarter of the acetabular rim, and the exit point was the intersection of the vertical extension line of S1 superior articular process and the horizontal median line of S1 transverse process. Screws with diameter of 6.5 mm and 7.3 mm and length of 90 mm were implanted into the left and right sides of the pelvic models, respectively. The implantation was observed. CT scan was performed when penetrating of channel was suspected.
resultsNone of the implanted screws perforated the tunnel, but 6.0% (3 models) of the screws were too long and a little bit penetrated (< 4 mm) behind the back of the tunnel, which was found in small models.
conclusionThe NISS implantation is simple, safe and accurate, but individualized screw implantation with appropriate diameter and length should be more accurate. TRIAL REGISTRATION NUMBER: WXSJY-LY-2020-00216, date of registration: June 5, 2020, retrospectively registered.
