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

backgroundThis study used three-dimensional computed tomography (3D-CT) to evaluate the targeted positions of rectangular bone tunnels created using a rectangular retro-dilator (RRD) in revision anterior cruciate ligament (ACL) reconstruction, with the aim of assessing the accuracy of the technique in bone tunnel creation at the target position.

methodsParticipants were 30 patients who underwent revision ACL reconstruction using an RRD. Based on 3D-CT images, the positions of the primary and revision tunnels were qualitatively evaluated according to the Magnussen classification, the quadrant method, and whether they were in the anatomical tibial attachment site of the ACL. Furthermore, coordinate data obtained by the quadrant method for the positions of the primary and revision tunnels were compared with anatomical and targeted ligament attachment sites.

resultsAll femoral revision tunnels were Type I according to the Magnussen classification. Qualitative evaluation of the tibial tunnels showed that the tunnel centres fell within the anatomical ACL attachment site in all patients. The femoral and tibial tunnel positions did not significantly differ from the targeted position, and both variances in the positions of the revision tunnels were significantly smaller than those of the primary tunnels.

conclusionsThe findings suggest that use of an RRD can create rectangular tunnels at the targeted position with a high rate of success in revision. In this study, the revision ACL reconstruction using an RRD allowed more anatomical positioning of bone tunnels than the primary reconstruction.
