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

backgroundThere are no reports on global research status of gastroenterology and hepatology (GI). This study was conducted to reveal the current global research status and trends in GI.

methodsArticles published during 2009 to 2018 in international GI journals were retrieved from the PubMed database. The top 20 countries by output were determined. The gross domestic product (GDP) of each country was also retrieved to figure out the correlation between outputs in GI and economy. The 5 highest-ranking countries were compared in the number of total articles, articles per capita, articles published in top journals, the accumulated impact factor (IF), and average IF. Total articles and articles per capita of the 5 countries were conducted time-trend analysis. The frequently-used terms in titles and abstracts of articles published in 2009 and 2018 were retrieved to conduct co-occurrence analysis to figure out the change of research highlights in GI.

resultsA total of 120,267 articles were included, of which 116,485 articles were from 20 highest-output countries. There was a positive correlation between output and GDP (r = 0.921, P < .001). The USA, Japan, China, Italy, and the UK were the 5 highest-ranking countries. The USA was the largest contributor with 26,215 articles, accounting for 17.4% of the total, but with no significant increasing trend (P = .122). Other 4 countries all showed increasing trends (all P < .001). For articles per capita, Italy ranked 1st among the 5 countries with 1591.0 articles per 10 million. The USA showed a decreasing trend (P = .026), other 4 countries all showed increasing trends (all P < .001). The UK had the highest average IF (6.685). For change of research highlights, it is more inclined to research of endoscopy, inflammatory bowel diseases, and nonalcoholic fatty liver disease.

conclusionIt is delightful that the global research output in GI field would be continuingly increased as the major highest-output countries showed increasing trends. However, the developing countries fell behind both in quantity and quality when compared with developed countries.
