Assessment of consistency between peer-reviewed publications and clinical trial registrations in nursing journals.

Background: The inconsistencies between randomized clinical trials (RCTs) registrations and peer-reviewed publications may distort trial results and threaten the validity of evidence-based medicine. Previous studies have found many inconsistencies between RCTs registrations and peer-reviewed publications, and outcome reporting bias is prevalent.

Aims: The aims of this review were to assess whether the primary outcomes and other data reported in publications and registered records in RCTs of nursing journals were consistent and whether discrepancies in the reporting of primary outcomes favored statistically significant results.

Correlates of Physical Activity in Colorectal Cancer Patients Based on Health Promotion Model.

Background: Increasing attention is being given to physical activity in colorectal cancer patients. Some studies have explored a few correlates of physical activity separately. A contemporary study based on the Health Promotion Model may systematically broaden the understanding of physical activity in colorectal cancer patients.

Empirical evidence for outcome reporting bias in randomized clinical trials of acupuncture: comparison of registered records and subsequent publications.

Background: Outcome reporting bias has received widespread recognition and been considered to pose two threats to the validity of clinical decision making because they overestimate the effect of treatments or distort the results of trials. However, the problem of outcome-reporting bias has not been systematically studied among randomized clinical trials of acupuncture. Our objectives were to evaluate the consistency between the registered records and subsequent publications with respect to outcomes and other data as well as to determine whether outcome-reporting bias favors significant primary outcomes.
