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

purposeThis study aimed to investigate differences in retinal blood flow leading to visual recovery in cases of macular detachment in rhegmatogenous retinal detachment (RRD). STUDY

designObservational, retrospective case series.

methodsWe studied 64 eyes diagnosed with unilateral RRD with macular detachment that underwent pars plana vitrectomy from May 2010 to July 2015 at the Department of Ophthalmology, Nagasaki University Graduate School of Biomedical Sciences. We retrospectively measured visual acuity, blood pressure, intraocular pressure, and retinal blood flow using laser speckle flowgraphy (LSFG) preoperatively and at 1, 3, 6, and 12 months postoperatively.

resultsLogMAR visual acuity significantly improved one month after surgery (p<0.001. Friedman test with post-hoc test Bonferroni correction). The average mean blur rate (MBR) significantly improved three months after surgery compared to before surgery (95.9±26.0%, p<0.001). A significant correlation was observed between logMAR visual acuity and MBR changes at 1 month (r=- 0.42, p=0.007), 3 months (r=- 0.46, p=0.003), 12 months (r=- 0.32, p=0.03).

conclusionWhen vitrectomy is performed for RRD, the retina is repositioned, resulting in significant improvements in visual acuity and retinal blood flow. TRANSLATIONAL RELEVANCE: Visual acuity recovery is correlated with the recovery of retinal blood flow.
