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 report two cases with retinitis pigmentosa (RP) who underwent vitreo-retinal surgery and developed severe retinal atrophy. OBSERVATIONS: Case 1 was a 36-year old man who underwent 20-gauge pars plana vitrectomy (PPV) for a macular hole (MH), and Case 2 was a 71-year-old man who also underwent 20-gauge PPV for an epiretinal membrane (ERM). During 13 years follow-up period, severe retinal atrophy developed near the macula that progressed rapidly and the best-corrected visual acuity (BCVA) was reduced to 1.1 logarithm of the minimum angle of resolution (logMAR) units in the MH case and to no light perception in the ERM case. CONCLUSIONS AND IMPORTANCE: An unexpected severe retinal atrophy can develop long after vitreo-retinal surgery in RP patients.
