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

Purpose: To correlate the optical coherence tomography (OCT) based morphological patterns of diabetic macular edema (DME) and prognostic biomarkers with severity of anaemia in patients with diabetic kidney disease (DKD). Patients and Methods: Single centre, observational cross sectional study of 42 eyes of 42 patients with DME and DKD. Eyes were divided into 2 groups: Group A (Haemoglobin level above 10 g% and group B with haemoglobin less than 10 g%). The OCT pattern and biomarkers were compared between the two groups. Results: Mean age of the patients was 56.9 ± 8.1 (range 42-79). Out of 42 participants, 22 patients had hemoglobin level more than 10g%(group A) while 20 patients had hemoglobin less than 10g%(Group B). The most common morphological pattern seen was combination of cystoid macular edema (CME) with diffuse retinal thickening (DRT) in both groups. Disruption of the external limiting membrane (ELM) and ellipsoid zone (EZ) was found to be associated with lower hemoglobin levels (p= 0.0155 and p= 0.0154 respectively). None of the other OCT biomarkers showed correlation with hemoglobin levels. Conclusion: CME with DRT is the most common morphological pattern of macular edema seen in DKD patients with anemia. ELM-EZ disruption can be considered as important biomarker of anaemia in patients with DKD.
