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

purposeWe aimed to determine the correlation between optical coherence tomography (OCT)- and demographic features and baseline best corrected visual acuity (BCVA) in treatment-naïve patients with retinal vein occlusion (RVO).

methodsThis was a cross-sectional posthoc analysis of OCT images that included RVO patients from two prospective, open-label, multicentre studies. The morphological grading was done manually, in the standardized setting of a reading centre. Main outcome measure was the estimated difference in Early Treatment Diabetic Retinopathy Study letters associated with each individual biomarker.

resultsIncluded were 381/301 treatment-naïve patients with BRVO/CRVO. For BRVO, statistically significant correlations with BCVA were seen for a 100 µm increase in central subfield thickness (CST; -3.1 letters), intraretinal cysts at centre point (CP; +4.1), subretinal fluid (SRF) at CP (+3.0) and hyperreflective foci (HRF) at the central B-scan (-2.2). In CRVO, a 100 µm increase in CST was associated with a loss of -3.4 letters. In the total cohort, 100 µm increase in CST, SRF at CP and HRF at the central B-scan correlated with a difference of -3.2,+3.2 and -2.0 letters. A 10-year increase in age and female gender yielded a -2.0 and -2.5 letter decrease in the total cohort. Adjusted multiple R

conclusionsOf all parameters studied, only CST and age were consistently associated with worse BCVA in treatment-naïve RVO patients. Morphology on OCT explained only a modest part of functional loss in this patient cohort.
