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
Purpose: To compare button position following femoral fixation of an anterior cruciate ligament (ACL) graft using fixed-loop cortical suspension device vs. an adjustable-loop device. Subsequently, to assess the association of button position-related factors and revision ACL reconstruction. Methods: This was a retrospective cohort study of consecutive patients undergoing ACL reconstruction using fixed-loop (Endobutton CL) and adjustable-loop cortical suspension device (Ultrabutton) for femoral fixation in a single institution between 2009 and 2022. Demographic and operative characteristics were recorded. To assess soft tissue interposition the distance between the button and the lateral femoral condyle (LFC) was measured on X-rays made on the first post-operative day. Other measurements included button angle, relative position (anterior/middle/posterior), and button migration (assessed using most recent X-rays). Results: Overall, 244 patients were included in the study. 59% of patients in the fixed-loop group and 41% in the adjustable-loop group. Hamstrings autograft was utilised most commonly (91%), while the rest of the procedures included allografts. A significantly shorter button distance from the LFC was noted in the post-operative Antero-posterior (AP) X-ray of the adjustable-loop button, 0.44 ± 0.52 mm versus 0.72 ± 0.84 mm, respectively ( Conclusions: Adjustable-loop cortical suspension devices for femoral fixation of an ACL reconstruction were associated with lower revision rates and a lower button-LFC distance when compared to fixed-loop devices. Level of Evidence: Level III, retrospective comparative cohort study.
