1 · What the graph read from it

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.

2 · The registry

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

purposePosterior pelvic ring stabilization is technically demanding due to the complex local anatomy and limited osseous corridors. Advances in 3D navigation may allow for new screw trajectories previously infeasible with conventional fluoroscopy.

methodsA finite element model (FE) of a pelvis (Synbone LSS4060/Hard

resultsConventional transsacral screws (Variants I-II) demonstrated the most uniform stress distribution and lowest peak stresses (7.17 MPa). Among novel configurations, Variant III achieved favorable compressive load transfer and lower shear stresses. Variant IV exhibited the highest overall stress (17.80 MPa), while Variant V demonstrated intermediate behavior.

conclusionThe proposed 3D-navigated oblique screw pathways are anatomically feasible and may offer biomechanical advantages under certain conditions. These findings support further validation using cadaveric and clinical studies.
