Finding Canadian cancer clinical trials on the Internet: an exploratory evaluation of online resources.
Article in CMAJ : Canadian Medical Association journal = journal de l'Association medicale canadienne, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundOnline information about the availability of clinical trials promises to enhance the accrual of patients into trials. The primary objective of our study was to assess the completeness of online databases of breast cancer clinical trials available in Canada.
methodsEligible online resources were identified through a search of MEDLINE (articles published from 1966 to January 2002), an Internet search with Google, examination of Web sites of cancer organizations and information from experts. Resources were included if they contained information about open, active cancer clinical trials available in Canada. Web sites reviewed were not limited to those based in Canada. For each eligible resource, the number of listed trials and the proportion of trials identified were calculated.
resultsOf 30 Web sites identified, 8 met all of the inclusion criteria; 3 were based in Canada and 5 in the United States. The total number of breast cancer trials identified as being available in Canada was 28. The Physician Data Query (PDQ) Clinical Trials Database of the US National Cancer Institute (cancer.gov/search/clinical_trials) identified 86% (24/28). The database of the National Cancer Institute of Canada Clinical Trials Group (NCIC CTG) (ctg.queensu.ca) identified 29% (8/28) of the available breast cancer trials. CenterWatch Clinical Trials Listing Service (centerwatch.com) identified 4% (1/28).
interpretationIf the PDQ database included all of the NCIC CTG trials, it would become the most complete database of breast cancer clinical trials currently available in Canada. Online cancer data sources should strive to make access to clinical trials simpler and more reliable, particularly for residents of the country where the trial is to be conducted.
