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 investigate periostin (PN) and tenascin-C (TNC) expression in the aqueous humor and trabeculectomy specimens of patients with neovascular glaucoma (NVG) secondary to proliferative diabetic retinopathy (PDR).

methodsThis study enrolled 37 eyes of 37 patients who were grouped into (1) NVG secondary to PDR (NVG; n = 8); (2) PDR without NVG (PDR; n = 9); (3) primary open-angle glaucoma (POAG; n = 11); and (4) cataract surgery patients as a control group (CG; n = 9). Aqueous humor samples were collected from the anterior chamber at the start of surgery or intravitreal injection of anti-VEGF drug. The concentrations of PN, TNC, VEGF, and TGF-β2 (transforming growth factor-beta 2) were measured by ELISA. Sclerostomy tissues containing trabecular meshwork were obtained from two NVG patients and a POAG patient who underwent trabeculectomy surgery. Immunohistochemical analyses were performed to determine the localization of PN and TNC expression in the sclerostomy tissues.

resultsPN and TNC-C levels were below detection threshold in the POAG and CG groups. The NVG group had significantly higher levels of PN and TNC compared with the PDR group (84.7 ng/ml vs 2.2 ng/ml and 18.5 ng/ml vs 4.6 ng/ml, respectively; p < 0.05). There was a significant correlation between the levels of PN and TNC-C in the NVG group (r = 0.86, p < 0.05). We found significant expression of PN in the trabecular meshwork and Schlemm's canal of sclerostomy tissues excised from patients with NVG.

conclusionsIncreased PN and TNC expression suggests their possible involvement in the pathogenesis of NVG secondary to PDR.
