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

Effects of Conbercept combined with retinal photocoagulation on macular edema secondary to branch retinal vein occlusion (BRVO) were investigated. A total of 98 patients (98 eyes) with macular edema secondary to BRVO were collected. The central macular thickness (CMT), incidence rate of complications after treatment and best corrected visual acuity (BCVA) were recorded. Also the factors affecting visual recovery of patients were analyzed. At 1 week, 1 month, 3 months and 6 months after treatment, the BCVA in both groups was significantly superior to that before treatment (P<0.05). In the combination group and laser group, the logarithm of the minimum angle of resolution (logMAR) of BCVA increased from 0.84±0.47 to 0.34±0.10 and from 0.89±0.49 to 0.45±0.14, and CMT declined from 559.5±152.7 to 267.8±19.8 µm and from 570.3±172.6 to 314.7±18.4 µm. It was observed that at 1 week, 1 month, 3 months and 6 months after treatment, the BCVA in combination group was obviously better than that in laser group (P=0.008, P<0.001, P=0.004, P<0.001, respectively), while CMT in combination group was obviously smaller than that in laser group (P=0.009, P=0.002, P<0.001, P<0.001). Conbercept with retinal photocoagulation can effectively improve the visual acuity and reduce the CMT. The visual recovery of patients after treatment is related to the BCVA before treatment, decreased value of CMT at 1 month after treatment and integrity of external limiting membrane (ELM).
