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

backgroundAs traditional methods have become increasingly difficult, the Internet offers a mechanism for conducting survey research quickly and efficiently. However, the validity of this research depends on the ability of respondents to accurately report health status. We used a large Internet-based inflammatory bowel disease (IBD) cohort to validate self-reported IBD against physician reports.

methodsBetween June 22, 2012, and April 01, 2013, all participants of CCFA Partners (n = 6681) were invited to participate, and 450 were selected by random stratified sampling. We sent physicians a survey to confirm IBD diagnosis and characteristics. We used descriptive statistics to compare data.

resultsA total of 4423 participants (66%) indicated interest. Of 450 selected, 261 (58%) consented, and physician reports were obtained for 184 (71%). Physicians confirmed IBD status in 178 (97%) and type in 171 (97% of confirmed). The matching between patient and physician reports for Crohn's disease (CD) was 82% for disease location, 89% for the presence of perianal disease, and 46% for disease behavior. For ulcerative colitis (UC), disease location matched 54% of the time. Physician reports confirmed the status of ever having bowel surgery for 97% of CD and 94% for UC and confirmed current pouch or ostomy in 84% of CD and 81% of UC.

conclusionsSelf-reported IBD in CCFA Partners is highly accurate, and participants are willing to release medical records for research. Self-reported phenotypic characteristics were less valid. The validity of IBD diagnoses among the participants of CCFA Partners supports the use of this cohort for patient-centered outcome research.
