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
Background: Use of syndesmotic suture button fixation has gained in popularity for treating an injury to the tibiofibular syndesmosis. This biomechanical study used a cadaveric model to simulate in vivo loading conditions to assess the impact of the placement of a syndesmotic stabilization construct using a suture button device. Methods: Biomechanical fixation stability with suture button device (TightRope; Arthrex, Naples, FL) placed at 4 distances from the tibiotalar joint line (0.5, 1.5, 2.5, and 3.5 cm) and 3 trajectories (anterior, medial, and posterior) were studied using cadaveric lower extremities with created syndesmotic injuries. Nondestructive testing was conducted on a biaxial servo-hydraulic load frame. The load application consisted of 2 portions: (1) axial compression simulating weightbearing and (2) external rotation of the ankle (up to 12 degrees and under 7.5 Nm) around the long axis of the tibia combined with weightbearing. Fibular motion and syndesmotic widening were tracked using motion analysis to quantify stability. Results: Fixation placed at 0.5 or 1.5 cm from the joint line in medial or posterior trajectories resulted in the lowest increases in fibular rotation under loading. More proximal or anterior placements led to increased fibular motion and decreased rotational stability. Ankle width changes were minimal in most groups, although slightly increased widening occurred at proximal and anterior placements. Conclusion: Placement of the syndesmotic suture button fixation 0.5-1.5 cm of the joint line in medial or posterior orientations provides the most rotationally stable fixation in a cadaveric model. These findings support flexibility in syndesmotic suture button fixation positioning when hardware constraints limit ideal placement.
