Changes in the ganglion cell complex thickness after anti-VEGF treatment for diabetic macular edema.

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.
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 assess tomographic ganglion cell complex changes in patients with diabetic macular edema treated with intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF).
methodsWe analyzed data from 35 eyes of 35 previously untreated patients in whom diabetic macular edema improved after three loading doses of anti-VEGF injection and who did not receive repeated injections. We recorded spectral domain-optical coherence tomography assessments of ganglion cell complex and central macular thickness at baseline and monthly for three months, and on the sixth and ninth month after treatment. We compared the results with those of the unaffected eyes in the same patients and with those in a control group of patients with diabetic macular edema who were untreated.
resultsThe mean age of the patients in the treatment group was 60 ± 4.38 years. The foveal thicknesses measured using optical coherence tomography decreased significantly from baseline to the third month post-injection (p<0.05). The mean ganglion cell complex thickness was 115.08 ± 16.72 µm before the first injection and 101.05 ± 12.67 µm after the third injection (p<0.05). The mean ganglion cell complex was 110.04 ± 15.07 µm on the sixth month (p>0.05) and 113.12 ± 11.15 µm on the ninth month (p>0.05). We found a significant difference between the patients and the control group in terms of mean ganglion cell complex thickness on the second- and third-months post-injection (p<0.05).
conclusionOur study showed that the ganglion cell complex thickness in patients with diabetic macular edema decreased after the anti-VEGF injections. We cannot ascertain whether the ganglion cell complex thickness decreases were due to effects of the anti-VEGF agents or to the natural disease course.
