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 evaluate corneal endothelial cell density (ECD) in patients with dry eye disease (DED) compared to an age-matched control group.

designCross-sectional, controlled study.

methodsThis study included 90 eyes of 45 patients with moderate to severe DED (aged 53.7 ± 9.8 years) and 30 eyes of 15 normal controls (aged 50.7 ± 9.8 years). All subjects had a complete ophthalmic evaluation including symptom assessment using the Ocular Surface Disease Index (OSDI) and corneal fluorescein staining. In addition, laser scanning in vivo confocal microscopy was performed to measure the density of the following parameters in the central cornea: endothelial cells, subbasal nerves, and subbasal immune dendritic cells.

resultsCorneal ECD was significantly lower in the DED group (2595.8 ± 356.1 cells/mm(2)) than in the control group (2812.7 ± 395.2 cells/mm(2), P = .046). The DED group showed significantly lower corneal subbasal nerve density (17.1 ± 6.9 mm/mm(2)) compared to the control group (24.7 ± 4.4 mm/mm(2), P < .001). Dendritic cell density was significantly higher in the DED group than in the controls (111.7 ± 137.3 vs 32.0 ± 24.4 cells/mm(2), respectively, P = .002). There were statistically significant correlations between corneal ECD and dry eye severity parameters including the OSDI score (rs = -0.26, P = .03), and corneal fluorescein staining (rs = -0.28, P = .008).

conclusionsThere is a significant reduction in corneal ECD in DED that correlates with clinical severity of the disease.
