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

purposeTo explore the relevance of scientific production on glaucoma using bibliometric tools.

designBibliographic study.

participantsOriginal articles published from 1900 through 2019.

methodsWe performed a search in Web of Science for documents published between 1900 and 2019. We used bibliometric indicators to explore documents production, dispersion, distribution, time of duplication, and annual growth, as characterized by Price's law of scientific literature growth, Lotka's law, the transient index, and the Bradford model. We also calculated the participation index of different countries and institutions. Finally, we explored with bibliometric mapping the co-occurrence networks for the most frequently used terms in glaucoma research.

main outcome measuresBibliometric indicators for individuals, institutions, and countries.

resultsA total of 33 631 original articles were collected from the timeframe 1900 through 2019. Price's law showed an exponential growth. Scientific production was adjusted better to exponential growth (r = 0.967) than linear growth (r = 0.755). Literature on glaucoma research increased its growth in the last 30 years at a rate of 5.1% per year with a production that doubled its size every 13.9 years. The transience index was 60.08%; this indicates that most of the scientific production is the output of very few authors. Bradford's law showed a high concentration of articles published in a small core of specialized journals. Lotka's law indicated that the distribution of authors is concentrated heavily in small producers. The United States and University of London demonstrated the highest production of original articles. Map network visualization showed the generated term map detailing clusters of closely related terms.

conclusionsGlaucoma literature has grown exponentially. A very high rate of transience was found that indicates the presence of numerous authors who sporadically publish on this topic. No evidence of a saturation point in the glaucoma literature was observed.
