Antegrade versus retrograde screw fixation of anterior column acetabular fractures: a biomechanical in vitro study.
Article in European journal of trauma and emergency surgery : official publication of the European Trauma Society, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07515092 (Virtual Reality-Based Simulation Training for Antegrade Anterior Column Acetabular Screw Placement in Orthopedic Residents), which is not on this map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
backgroundTo compare the mechanical strength of antegrade versus retrograde lag screw fixation of anterior column acetabular fractures.
methodsStandardised anterior column fractures were created in synthetic pelvis models and stabilised by either antegrade (ANTE, n = 4) or retrograde (RETRO, n = 4) anterior column screw fixation. In a validated setup, a cyclic loading protocol was applied with increasing axial force (750 cycles, 250-750 N) followed by load to failure. Construct survival, energy absorbed, construct stiffness, and load to failure were assessed. Descriptive and opto-metric methods were used to describe the mode of failure.
resultsAll constructs failed with loads below 1500 N. With regard to energy absorbed until failure, the ANTE group resisted to 3.763 × 10
conclusionsIn this in vitro mechanical study, antegrade screw fixation of an anterior column acetabular fracture was not different in construct survival, load to failure, stiffness, and mode of failure when compared to retrograde screw fixation.
