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

The number of authors per manuscript in peer-reviewed medical journals has increased substantially in the last several decades. Several reasons have been offered to explain this authorship growth, including increased researcher collaboration, honorary authorship driven by increased pressures for funding and promotion, the belief that including senior authors will facilitate publication, and the growing complexity of medical research. It is unknown, however, whether authorship has grown over time due to growing complexity of published academic articles, in which case growth could be warranted, or whether it has grown due to pressures of funding and academic promotion, which have created "authorship inflation." To answer this question, we analyzed data on authorship count, study type, and size of study population for the first 50 original articles published in each decade during 1960-2010 in 3 major medical journals. Within each type of study we considered (eg, randomized trials, observational studies, etc), average authorship rose more than 3-fold during this period. Similar growth persisted after adjustment for changes in study population sizes over time. Our findings suggest that increasing research complexity is an inadequate explanation for authorship growth. Instead, growth in authorship appears inflationary.
