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

purposeThe recently published seminal dry eye workshop proceedings defined Lissamine Green (LG), an organic dye, as a gold standard for demonstrating ocular surface staining. The purpose of the current study was to determine the optimal parameters of 1% LG instillation for the ocular surface examination in dry eye patients.

designProspective and observational quality improvement study.

methodsA quality improvement study evaluated 16 eyes from eight dry eye patients with different levels of severity. LG (1%), in three volumes (5, 10, and 20 μl) was instilled into the conjunctival cul-de-sac, and four masked observers with different levels of clinical expertise examined the patients with and without red filter. The staining pattern of the conjunctiva and cornea was documented with the Oxford scale within 4 min of LG instillation. Optimal volume and inter-observer reliability were assessed.

resultsAll dye volumes were tolerated well by all patients. Experienced observers preferred 10 μl volume because of the ease of examination and accuracy. Although instillation of 20 μl yielded similar scores as 10 μl, it resulted in overflow of the lid and facial skin staining. The use of red filter significantly improved reading scores (P<0.01). Inter-observer reliability was higher for conjunctival scores than for corneal scores for all patients. The highest reliability was demonstrated with 10 μl volume and increased with greater experience of the observer.

conclusionsOcular surface examination with instillation of 10 μl 1% LG has good inter-observer reliability and is well tolerated. Observation through a red filter facilitates the examination.
