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

backgroundIdiopathic epiretinal membranes (ERMs) often cause metamorphopsia and the progressive loss of central visual function, which seriously affect quality of life. We aimed to map the distribution pattern of idiopathic ERMs in China and to examine the factors affecting the surgical choices of multicenter surgeons.

methodsA national ophthalmologist-oriented questionnaire was administered, applied with a multistage probability sampling method. Data of essential characteristics, including age, professional title, residence, and perioperative and postoperative care, were gathered. All the data are expressed as odds ratios (ORs) and 95% confidence intervals (CIs). The histogram and choropleth map were generated by Excel 2016.

resultsIn total, 1,137 (85.2%) valid responses were returned with maximized response and completion rates. The study showed that monthly admission numbers, and preoperative and postoperative care varied significantly across different regions in China. Generally, the monthly patient admission numbers were lower in the Western region than the Eastern region. However, patients in the Eastern region had longer preoperative waiting periods and shorter hospital stays.

conclusionsThe epidemiology of idiopathic ERMs varied significantly across different regions in China. The distribution pattern of ERM in China and the overview of the factors affecting the surgery approaches of multicenter surgeons were shown. The findings of this study will contribute to the formulation of medical policies, and provide insights into the healthcare environments across China.
