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

Purpose: To demonstrate the role of ocular lymphatic involvement in aiding the drainage and resolution of subconjunctival hemorrhage. Methods: We present the case of a 63-year-old Caucasian female who developed a subconjunctival hemorrhage following the administration of a subconjunctival anesthetic during cataract surgery. Intraoperative optical coherence tomography was utilized to image these structures within the deep and middle conjunctival-Tenon's space. Results: Subconjunctival hemorrhage was visualized and saccular blood-filled structures developed adjacent to sites of hemorrhage. Intraoperative optical coherence tomography confirmed the presence of blood within structures containing partitions reminiscent of valvular leaflets, indicating their lymphatic origin. Rapid resolution of the subconjunctival hemorrhage was noted during the immediate postoperative period. Conclusion: Subconjunctival hemorrhage may have its resolution assisted by conjunctival lymphatic vessels. Our findings confirm that lymphatic structures may play an under-appreciated role in assisting the clearance of macromolecules from the subconjunctival space.
