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 assess efficacy of intravitreal conbercept (IVC) injection in combination with panretinal photocoagulation (PRP)

methodsForty-eight patients with SNPDR without ME (56 eyes) were divided into the PRP group and IVC+PRP group (the pulse group) in this retrospective clinical study. Conbercept was intravitreally administered to patients in the pulse group 1wk before treatment with PRP and followed up for 1, 3, and 6mo. The best-corrected visual acuity (BCVA, logMAR), center foveal thickness (CFT), visual acuity (VA) improvement, and adverse reactions were compared between groups.

resultsIn the PRP group, the BCVA reduced at 1 and 3mo before improving at 6mo. In the pulse group, baseline BCVA decreased continuously at 1mo, increased at 3 and 6mo. BCVA in the pulse group was better than that in the PRP group at 1, 3, and 6mo. There was an increase in CFT in the PRP group during follow-up compared with baseline. In the pulse group, CFT was increased at 1mo relative to baseline, steadily decreased to the baseline level at 3 and 6mo. There was a more significant reduction in CFT in the pulse group during follow-up compared with the PRP group. The effective rates of VA in the PRP and the pulse groups were 81.48% and 100%, respectively.

conclusionAs PRP pretreatment, a single dose of IVC administration has beneficial effects for preventing PRP-induced foveal thickening and increasing VA in patients with SNPDR without ME.
