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

objectiveTo determine if the PubMed and Ovid MEDLINE clinical queries (which were developed in the publishing year 2000, for the purpose categories therapy, diagnosis, prognosis, etiology, and clinical prediction guides) perform as well when searching in current publishing years.

methodsA gold standard database of recently published research literature was created using the McMaster health knowledge refinery (http://hiru.mcmaster.ca/hiru/HIRU_McMaster_HKR.aspx) and its continuously updated database, McMaster PLUS (http://hiru.mcmaster.ca/hiru/HIRU_McMaster_PLUS_projects.aspx). This database contains articles from over 120 clinical journals that are tagged for meeting or not meeting criteria for scientific merit and clinical relevance. The clinical queries sensitive ('broad') and specific ('narrow') search filters were tested in this gold standard database, and sensitivity and specificity were calculated and compared with those originally reported for the clinical queries.

resultsIn all cases, the sensitivity of the highly sensitive search filters and the specificity of the highly specific search filters did not differ substantively when comparing results derived in 2000 with those derived in a more current database. In addition, in all cases, the specificities for the highly sensitive search filters and the sensitivities for the highly specific search filters remained above 50% when testing them in the current database. DISCUSSION: These results are reassuring for modern-day searchers. The clinical queries that were derived in the year 2000 perform equally well a decade later.

conclusionThe PubMed and Ovid MEDLINE clinical queries have been revalidated and remain a useful public resource for searching the world's medical literature for research that is most relevant to clinical care.
