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

purposeVisualizing the check ligaments of extraocular muscles is essential to understand their role as stabilizers of the extra-ocular muscles, acting as their antagonists. Although all extraocular muscles are expected to have corresponding check ligaments, this is not consistently documented in anatomical literature. This study aims to clarify the check ligaments using acquired high-resolution true color sectioned images and surface modeling.

methodsFrom the sectioned images of one male cadaver, the check ligaments and related structures were outlined and surfaces models were reconstructed using 3D Slicer and Maya to analysis their morphology.

resultsThe seven check ligaments corresponding to the seven extraocular muscles, along with the supporting ligaments, were clearly delineated. Previously unrecognized attachment points of the check ligaments, especially to fasciae, were highlighted. In addition to exploring in more detail the tendinous role of Whitnall’s ligament and Lockwood’s ligament, we focused on the morphology of the ligaments on the lower eyelid.

conclusionThrough the reconstruction of surface models based on true color sectioned images, we were able to differentiate all extraocular check ligaments and supporting structures, aligning to their respective roles.
