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

purposeTo compare visual and anatomic outcomes in eyes with type 2 idiopathic macular telangiectasia (Mactel) treated with either intravitreal bevacizumab (IVB), observation, or pars plana vitrectomy (PPV) with internal limiting membrane removal.

methodsRetrospective, consecutive, interventional case series of phakic patients with Mactel. Best-corrected Snellen visual acuity (BCVA) and complete ophthalmic exam was obtained prior to treatment and at subsequent 3-month intervals for a minimum of 6 months. Fluorescein angiographic and spectral-domain optical coherence tomography features were examined, and compared to BCVA at treatment initiation and follow-up.

resultsFifty-six eyes of 28 patients were evaluated. Mean age was 65 ± 12 years, and mean follow-up was 24 ± 13 months. Patients were treated with either observation (n = 33), IVB (n = 15), or PPV (n = 8). Mean number of treatments for the IVB group was 2.5 ± 3.5 intravitreal injections. No significant differences in BCVA change were observed between treatment groups via one-way ANOVA (p = 0.49). Presence of inner retinal cysts was not correlated to BCVA (p > 0.05). Discontinuous outer nuclear layer was significantly related to worse initial and final vision, but not to BCVA change.

conclusionIVB and PPV with ILM removal appear ineffective in improving visual outcome in eyes with non-proliferative Mactel. SD-OCT evidence of disrupted foveal outer nuclear layer is related to decreased BCVA, but not related to BCVA change following treatment.
