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 investigate the effect of tear film parameters on optical coherence tomography (OCT) signal strength index (SSI) in dry eye disease (DED) patients.

methodsThis cross-sectional study included 77 DED patients and 77 healthy controls. All participants underwent ocular surface index (OSDI) assessment, Schirmer I test, non-invasive break up time (NIBUT) measurement, and OCT imaging. SSI values from raster and optic nerve head (ONH) scans were recorded using the RTVue-100 device. Correlation and multivariate analyses were performed.

resultsDED patients exhibited significantly lower raster and ONH SSI values compared to controls (p < 0.001). SSI positively correlated with NIBUT and Schirmer, and negatively with OSDI scores (p < 0.001). NIBUT and OSDI were independent predictors of SSI in regression models.

conclusionTear film instability reduces OCT signal quality in DED, even without media opacities. Ocular surface optimization should be considered before OCT imaging to ensure accurate evaluation of measurements.
