Retinal Morpho-Functional Changes Following 0.19 mg Fluocinolone Acetonide Intravitreal Implant for Chronic Diabetic Macular Edema.
Observational study in Advances in therapy, 2021. 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
purposeTo evaluate morpho-functional outcomes of the intravitreal fluocinolone acetonide (FAc) implant.
methodsRetrospective, observational, single-center study. Primary endpoint was the mean change in central macular thickness (CMT) from baseline to month 1-3. Secondary endpoints included mean CMT change from baseline to month 4-8 and 9-14 and mean best corrected visual acuity (BCVA), photopic negative response (PhNR) and b-wave of flash full-field electroretinogram (ERG) changes from baseline to month 1-3, 4-8, and 9-14.
resultsFourteen patients (18 eyes) were included. Mean (standard deviation) CMT decreased from 473 (196) µm at baseline to 371 (163) µm at month 1-3 (mean difference - 102.3 ± 98.35 µm, 95% CI ± 46.4 µm; p < 0.0001) and this decrease tended to endure up to month 9-14. BCVA did not change significantly. There was an improvement in mean PhNR amplitude from 2.76 (1.65) µV at baseline to 3.73 (2.32) µV at month 1-3 (mean difference 0.91 (1.14) µV, 95% CI ± 0.54 µV, p = 0.003); b-wave amplitude improved from 8.83 (4.52) µV at baseline versus 10.05 (5.04) µV at month 1-3 (mean difference 1.22 (2.23) µV, 95% CI ± 1.08 µV, p = 0.0384). These ERG positive changes tended to endure up to month 9-14, although they did not reach statistical significance after month 3.
conclusionsIntravitreal FAc implant significantly improved anatomic as well as functional outcomes related to middle and inner retinal layers, known to be altered in diabetic retinopathy. Our findings support the hypothesis that intravitreal FAc implant may exert a protective effect in diabetic retinas with diabetic macular edema.
