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

aimTo investigate the safety and efficacy of intravitreal dexamethasone implants (Ozurdex

methodsThis was an audit retrospective review of medical records of patients with DME who switched to the DEX intravitreal implant. Patients were divided into 2 groups: patients naïve to antiangiogenic therapy and patients who were previously treated with anti-VEGFs. Data regarding demographics, changes in mean best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP) was collected over 6mo. The demographic data mean changes in BCVA, CMT, and IOP were compared. Six-month follow-up data of 47 patients (57 eyes), who either switched to DEX implant irrespective of response to previous treatments or were treatment naïve before receiving DEX implant, was collected.

resultsImprovement in mean BCVA was observed from 1-4mo after injection with a decreased effect at month 6 as expected, with better outcomes in naïve compared to non-naïve patients. A statistically relevant decrease in mean CMT was observed during the follow-up period. An increase in mean IOP was observed in the first 2mo after DEX therapy. The mean number of injections of the overall population during the 6mo was 1.3. A subgroup analysis showed no relevant difference between phakic versus pseudophakic patients relative to measured outcomes. There was no cataract progression during the follow-up period and no adverse events reported.

conclusionThis real-life setting study shows that intravitreal DEX implant is effective and safe. The timings of greater therapeutic impact are concordant with previous studies and suggest that earlier treatment with corticosteroids may have an additional benefit in naïve patients.
