Disappearing act: decay of uniform resource locators in health care management journals.
Article in Journal of the Medical Library Association : JMLA, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
objectivesThis study examines the problem of decay of uniform resource locators (URLs) in health care management journals and seeks to determine whether continued availability at a given URL relates to the date of publication, the type of resource, or the top-level URL domain.
methodsThe authors determined the availability of web-based resources cited in articles published in five source journals from 2002 to 2004. The data were analyzed using correlation, chi-square, and descriptive statistics. Attempts were made to locate the unavailable resources.
resultsAfter checking twice, 49.3% of the original 2,011 cited resources could not be located at the cited URL. The older the article, the more likely that URLs in the reference list of that article were inactive (r = -0.62, P<0.001, n = 1,968). There was no difference in availability across resource types (chi(2) = 5.28, df = 2, P = 0.07, n = 1,786). Whether an URL was active varied by top-level domain (chi(2) = 14.92, df = 4, P = 0.00, n = 1,786).
conclusionsURL decay is a serious problem in health care management journals. In addition to using website archiving tools like WebCite, publishers should require authors to both keep copies of Internet-based information they used and deposit copies of data with the publishers.
