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

Cell lines represent an invaluable resource in modern science including basic and translational cancer research. Although there have been warnings over the past half century, the number of publications in the literature that erroneously used "non-existent" cell lines is still growing. For example, the Hep-2 cell line, first described in 1954 as laryngeal cancer cells, was reported as soon as in 1966 to be comprised of cervical adenocarcinoma cells derived via HeLa cell line contamination. Notably, the International Cell Line Authentication Committee (ICLAC) reported Hep-2 to be one among 488 misidentified cell lines, and one of 451 cell lines where no authentic stock is known. However, the number of laryngeal cancer research publications using the Hep-2 cell line has greatly increased over the past three decades. A comprehensive review of Hep-2 cell line misuse has been performed to identify the extent of the problem. 1,036 publications referenced in the MEDLINE database from 1954 to the first of January 2018 referred to the purported laryngeal origin of the Hep-2 cell line, with an increasing trend and with a peak of 93 publications in 2014. The rate of publications that focused on laryngeal cancer topics have increased over the past three decades to reach 80% in 2017. This increase was mainly driven by the remarkable productivity of Chinese researchers, of which English-language publications represented 76% of these articles in 2017. International collaborations and up-to-date national guidelines are needed.
