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 our findings in a case of pellucid marginal corneal degeneration (PMCD) in the left eye and keratoconus (KC) in the right eye, and to review earlier cases of PMCD and KC. OBSERVATIONS: A 45-year-old woman visited our hospital with a complaint of reduced vision in her right eye. She was predisposed to allergies since childhood and had a habit of rubbing her eyes. Based on the results of the corneal topographic study, we diagnosed her with KC in the right eye and PMCD in the left eye. We prescribed a rigid, gas permeable contact lens and treated her allergic conjunctivitis with ocular medications. Three years after her initial visit, she developed a corneal perforation in the left eye. The perforation was closed by conservative treatment consisting of therapeutic soft contact lens wear. One year after the cornea healed, the corneal astigmatism in the left eye was about one-half of what it was before the corneal perforation. Her corrected visual acuity improved to 1.0 with conventional spectacles. CONCLUSIONAND IMPORTANCE: We found a difference in the progression of KC and PMCD even when they occurred in same individual. We suggest that the atopic predisposition, which is considered a risk factor for acute hydrops in KC, to be a risk factor for acute hydrops and corneal perforation in eyes with PMCD.
