Comparison of conbercept and ranibizumab combined mitomycin C-augmented trabeculectomy for neovascular glaucoma.
Trial report in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 2 of them syntheses that pooled 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.
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 compare the efficacy and security of conbercept and ranibizumab combined with trabeculectomy and panretinal photocoagulation for neovascular glaucoma (NVG).
methodsOne hundred and sixty patients with NVG were randomly divided into a conbercept group comprised of 80 patients and a ranibizumab group comprised of 80 patients. The postoperative and preoperative visual acuities, intraocular pressures frequency of anti-glaucoma medications, and surgical complications were recorded. The expressions of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor (FLT-1), and placenta-like growth factor (PLGF) in the aqueous humor were determined using an enzyme-linked immunosorbent assay. Examining the fundus and obtaining photographs used indirect ophthalmoscopy. Kaplan-Meier and log-rank analyses estimated the success rates.
resultsAll patient follow-up periods were at 1 year. The differences observed in IOP and the frequencies of anti-glaucoma medications at various follow-up time points were not statistically significant (all P > 0.05). The differences observed in both the group visual acuities at various follow-up time points were not statistically significant (P > 0.05). Rates of surgery complications were 18.75% and 25.00% in the conbercept group and ranibizumab group, respectively. The expressions of VEGF, FLT-1, and PLGF significantly decreased (all P < 0.05). The recurrence percentages were 30.00% and 36.25% after conbercept and ranibizumab treatment, respectively.
conclusionThe conbercept effects were similar with that of ranibizumab. Intravitreal injection of conbercept was effective for NVG treatment, which provides a new therapeutic drug for NVG treatment.
