The Efficacy of Single-Dose Intravitreal Dexamethasone Implant for Diabetic Macular Edema Refractory to Anti-VEGF Therapy: Real-Life Results.
Article in Beyoglu eye journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesTo investigate the efficacy, safety, and side effect profiles of a single-dose intravitreal dexamethasone implant (IDI, Ozurdex) in patients with diabetic macular edema (DME) refractory to anti-vascular endothelial growth factor (VEGF) therapy.
methodsThis study included 101 eyes of 78 diabetic patients with DME that remained persistent despite administering at least six doses of anti-VEGF therapy. The patients were evaluated at baseline and were followed up monthly until the sixth month after the IDI injection. The primary outcomes were central foveal thickness (CFT) and best-corrected visual acuity (BCVA).
resultsThe mean number of anti-VEGF injection administered to patients was 6.50±0.33. One month after the last injection, the response to treatment was evaluated. IDI injection was performed approximately 1.14±0.08 months after the last anti-VEGF injection. After the IDI injection, BCVA value increased (p<0.001) and CFT value decreased (p<0.001). The peak effect of the IDI was observed in the second month after the injection. CFT values increased and BCVA values decreased from the beginning of the fourth month after the IDI injection. The recurrence rate of CFT elevation in the sixth-month follow-up was 57.4%. Moreover, we observed that high pre-injection CFT values were correlated with a high post-injection recurrence rate of CFT elevation (p<0.001).
conclusionThese findings suggest that the IDI injection significantly improves BCVA and CFT values in patients with DME refractory to anti-VEGF therapy. However, recurrence of CFT elevation may occur in >50% patients in the sixth month after the first injection.
