Quotation errors related to the Proximal Fracture of the Humerus Evaluation by Randomization (ProFHER) study.
Article in Shoulder & elbow, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
aimThe aim of this study was to assess the accuracy of quotations of the Proximal Fracture of the Humerus Evaluation by Randomization (ProFHER) study in the published literature.
methodsA literature search was performed from March 2015 to November 2019 to identify all papers that reference ProFHER since its publication. Full text articles were reviewed by two independent reviewers using a validated framework of assessing quotation errors. A kappa co-efficient was calculated to assess interobserver reliability of the reviewers.
resultsThere were 260 individual ProFHER quoted references within the 138 included articles. We identified 35/260 quotation errors (13%). Of these, 10/35 (29%) were major quotation errors and 25/35 (71%) minor quotation errors. There was substantial interobserver agreement when errors were classified. Of the 10 major errors, six quotations were not substantiated by the results of ProFHER and three were unrelated to ProFHER. One paper contained a quotation error that contradicted the results of ProFHER. Of the 25 minor errors, 19 oversimplified or generalised the conclusions of ProFHER and six contained numerical or grammatical errors.
conclusionThe current study demonstrated substantial inaccuracies in quotations of the Proximal Fracture of the Humerus Evaluation by Randomization study. Vigilance is recommended when quoting the literature and reviewing submitted papers in order to prevent the perpetuation of misquoted data.
