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

Objectives: To present three cases where the retrobulbar spot sign (RBSS) was observed, but central retinal artery occlusion (CRAO) was not confirmed. Methods: Transorbital sonography was employed to detect the presence of RBSS in all patients. Results: RBSS was detected in all three patients. However, only one patient had CRAO, with RBSS-positive findings in both eyes, although one eye showed normal function. The other two patients exhibited RBSS without evidence of CRAO. RBSS remained unchanged in all four eyes during the follow-up period. Conclusion: RBSS may not be specific to CRAO, as it was observed in non-CRAO cases. Further research is necessary to clarify its diagnostic significance and differentiate it from other pathologies.
