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

aimWe studied the use of patient/disease registries to recruit potential subjects for prospective clinical trials - describing the number, types and major benefits of using this approach.

methodsIn December 2013, we conducted a focused database search in PubMed, EMBASE, and Web of Science for studies (English language only) that used registries to recruit subjects for clinical trials published in 2004-2013. Of the 233 unique citations identified, 21 used registries to recruit subjects - 10 papers and 11 abstracts. Pearling and search for subsequent full papers of the abstracts identified 4 more papers.

resultsOur analysis, based on these 25 citations, showed that 14 are related to cancer, 3 to diabetes mellitus, 1 each to stroke, asthma, and celiac disease and 5 are disease neutral. Many types of registries (population-based cancer, quality improvement, disease-specific, web-based disease-neutral registries, local general practice registers, and national health database) are used to recruit subjects for clinical trials and uncover new knowledge. Overall, 16 registries are in the US, 4 in UK, 1 each in Canada, Spain, and Australia and 1 involved in many countries. Registries can identify very large number of subjects for screening for eligibility for clinical trials, especially in very large trials, rare disease trials, and trials involving minority patients.

conclusionsRegistries can retrospectively identify very large numbers of potential subjects for screening for eligibility and enrollment in prospective clinical trials. This matching can lead to more timely recruitment and help solve a major problem in conducting clinical trials.
