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

A 35-year-old woman underwent left external dacryocystorhinostomy (DCR) following a recent bout of left acute dacryocystitis. She had a right DCR 14 years earlier. Her relatively young age of presentation prompted suspicion of secondary nasolacrimal duct obstruction and, although the left lacrimal sac appeared macroscopically normal peroperatively, a lacrimal sac biopsy was taken. Histopathology revealed florid chronic inflammation, with abundant granular brown pigment and polarisable crystals suggestive of an exogenous material in the lacrimal sac mucosa compatible with mascara. After initial improvement, her epiphora has recurred 1-year postoperatively, but her ocular discharge has resolved. Mascara-induced conjunctival pigmentation is well established. However, there are very few published reports of nasolacrimal duct obstruction due to mascara. Since cosmetic application of mascara and kohl eyeliner is widespread, patients and practitioners should be aware of their potential to migrate into the lacrimal apparatus and cause chronic inflammation with secondary nasolacrimal duct obstruction.
