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

Superior oblique muscle of the eye is involved in depression, abduction and intorsion of the eyeball. Knowledge of its variations is useful for understanding and repairing strabismus cases and other visual problems. We report a rare unilateral variation of right superior oblique muscle. The superior oblique muscle had a normal origin. However, it had two insertions. Its tendon passed through the fibrous trochlea and was inserted to the sclera in a usual manner. In addition, it had an additional insertion to the roof of the orbit through an aponeurosis. We also observed the encroachment of the roof of the orbit by the frontal and ethmoidal air sinuses. The knowledge of these variations could be important to ophthalmologists.
