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

BACKGROUND We aimed to evaluate the efficacy and safety of pneumatic trabeculoplasty (PNT) and selective laser trabeculoplasty (SLT) in the treatment of primary open-angle glaucoma (POAG) and ocular hypertension (OHT). MATERIAL AND METHODS We randomly divided 120 cases (120 eyes) of POAG or OHT into 2 groups: PNT and SLT. The changes in anterior chamber angle, intraocular pressure (IOP), treatment effect, macular retinal ganglion cell complex (GCC) thickness, visual field, adverse reactions, and complications were observed before and 3 months after treatment. RESULTS In the PNT group, the opening range of anterior chamber angle at 1 week, 2 weeks, 1 month, and 3 months after surgery was significantly larger than that before surgery. In the SLT group, the open range of anterior chamber angle was significantly less than that before surgery at 1 week and 2 weeks after surgery. The open range of anterior chamber angle in the PNT group was significantly larger than that in the SLT group at 1 week, 2 weeks, 1 month, and 3 months after surgery. The mean IOP of the 2 groups decreased significantly after surgery. The postoperative mean IOP of the SLT group was significantly higher than that of the PNT group, and the decrease of IOP in the PNT group was significantly greater than that of the SLT group. The effective rate of the PNT group was higher than that of the SLT group. CONCLUSIONS Both PNT and SLT can reduce the IOP of patients with POAG and OHT. PNT appears to have better short-term treatment efficiency than SLT.
