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

backgroundMethodological quality and author internationality are increasing in orthopaedic surgery. The purpose of this study was to evaluate the methodological quality and author geography trends from 1994 to 2019 in high-quality foot and ankle journals.

methodsAnalyses of 1,242 foot and ankle publications in Foot and Ankle International, American Journal of Bone and Joint Surgery, and American Journal of Sports Medicine were done for 1994, 1999, 2004, 2009, 2014, and 2019. Articles were classified according to study type, level of evidence (LOE), and author's country of publication.

resultsThe most common clinical study was therapeutic (65.4). Significant increases were noted in the proportion of therapeutic (P < 0.01) and prognostic (P < 0.01) articles. The average LOE increased from 3.96 ± 1.01 to 3.19 ± 0.97 (P < 0.01). The proportion of Level I (P = 0.29) and level IV articles (P = 0.21) remained constant, level II (P < 0.01) and level III (P < 0.01) articles increased, and level V (P < 0.01) articles decreased. United States authorship decreased from 78.1% in 1994 to 44.8% in 2009, then remained constant through 2019 (P < 0.01).

conclusionThis study demonstrated an improvement in LOE of foot and ankle publications across a 25-year period in three high-quality orthopaedic journals. Increasing internationality was also observed.
