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

backgroundDiabetic nephropathy (DN) is not only an important microvascular complication of diabetes but also the main cause of end-stage renal disease. Ginkgo biloba has a variety of biological activities and has been widely used in China to treat kidney diseases such as DN. This article aimed to evaluate the efficacy and safety of G biloba in patients affected with DN in the early stage.

methodsThis protocol follows the preferred reporting items for systematic review and meta-analysis protocols and the recommendations of the Cochrane Collaboration Handbook. Seven electronic databases will be searched from inception to July 31, 2020. Two investigators will independently identify relevant randomized controlled trials, fetch data, and assess the risk of bias with tools provided by Cochrane. A comprehensive meta-analysis will be conducted with the Cochrane Collaboration software (Review Manager 5.3) for eligible and appropriate studies. Further, the evidence will be assessed with the Grading of Recommendations Assessment, Development, and Evaluation approach.

resultsThe results will be published in academic peer-reviewed journals, and the evidence gathered by this project will be dedicated to assessing the efficacy and safety of G biloba for DN patients in the early stage.

conclusionThis systematic review and meta-analysis will synthesize the available evidence to demonstrate the efficacy of G biloba in delaying the progression of patients with early DN. TRIAL REGISTRATION NUMBER: PROSPERO CRD42020166805.
