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
backgroundInjection laryngoplasty (IL) is a common procedure performed by the laryngologist to treat glottal insufficiency. It can be performed under general anaesthesia (GA) or as an office-based procedure. One of the common problems faced during IL is the disconnection between the injection needle and injection material syringe due to high-pressure effect. This may lead to leakage of the injectates especially when injecting high-viscosity materials such as calcium hydroxylapatite (CaHa) or injecting through hard fibrotic scar of the vocal fold. PURPOSE: Due to this recurring issue, we propose anti-reflux valve as a connector to link up these two devices. The function of anti-reflux valve is to ensure secure connection between these two devices and overcome the problem.
methodsThe anti-reflux valve that can be used is NeutraClearTM needle-free connector EL-NC1000 or MicroClaveTM clear connector. In our practice, these anti-reflux valves are used together with Integra MicroFrance straight malleable injection needle (0.5 mm diameter, 250 mm length) for IL under GA. However, any other injection needle suitable for IL may also be used with these anti-reflux valves.
resultsOur 3 years' experience has shown good outcome with no reported incidence of device detachment or leakage of injectates during IL procedure.
conclusionsAnti-reflux valve is a readily available device in the operating theatre or clinic and only involve simple preparation prior to IL. It is beneficial as an added device in IL procedure.
