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

purposeto describe a patient with a contractile peripapillary staphyloma and transient visual loss (TVL) that underwent repeated OCTA examination documenting disc contraction and increased peripapillary vessel density as the mechanism of TVL. OBSERVATIONS: a 28-year-old male presented multiple daily episodes of TVL for the last 5 years. Fundoscopic examination revealed a peripapillary staphyloma. The fundus photographs and SS-OCT demonstrated flattening of the posterior polo and crowding of the contracted optic disk, which became hyperemic with tortuous and dilated veins during visual loss episodes. OCTA showed temporary increased peripapillary vessel density, presumably from severe venous congestion leading to TVL during the contraction. CONCLUSION AND IMPORTANCE: increased peripapillary vessel density can be demonstrated by OCTA during TVL in contractile peripapillary staphyloma. These findings indicate that severe venous stasis during disc contraction is the cause of TVL.
