The continued problem of URL decay: an updated analysis of health care management journal citations.
Article in Journal of the Medical Library Association : JMLA, 2022. 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
Objective: This study updates a 2009 study which examined uniform resource locator (URL) decay in health care management journals and seeks to determine whether continued URL availability relates to publication date, resource type, or top-level domain. The authors also provide an analysis of differences in findings between the two study periods. Methods: The authors collected the URLs of web-based cited references in articles published in five health care management source journals from 2016 to 2018. The URLs were checked to see if they were still active and then analyzed to determine if continued availability was related to publication date, resource type, or top-level domain. Chi-square analysis was conducted to determine associations between resource type and URL availability, and top-level domain and URL availability. A Pearson's correlation was conducted to determine the relationship between publication date and URL availability. Results: There were statistically significant differences in URL availability across publication date, resource type, and top-level domain. Domains with the highest percentage of unavailable URLs were .com and .net, and the lowest were .edu and .gov. As expected, the older the citation, the more likely it was unavailable. The overall percentage of unavailable URLs decreased from 49.3% to 36.1% between studies. Conclusion: URL decay in health care management journals has decreased in the last 13 years. Still, URL decay does continue to be a problem. Authors, publishers, and librarians should continue to promote the use of digital object identifiers, web archiving, and perhaps study and replicate efforts used by health services policy research journals to increase continued URL availability rates.
