Physician characteristics associated with proper assessment of overstated conclusions in research abstracts: A secondary analysis of a randomized controlled trial.

ABSTRACT: OBJECTIVES:Little is known about the physician characteristics associated with appraisal skills of research evidence, especially the assessment of the validity of study methodology. This study aims to explore physician characteristics associated with proper assessment of overstated conclusions in research abstracts. DESIGN:A secondary analysis of a randomized controlled trial. SETTING AND PARTICIPANTS:We recruited 567 volunteers from the Japan Primary Care Association. METHODS:Participants were randomly assigned to read the abstract of a research paper, with or without an overstatement, and to rate its validity. Our primary outcome was proper assessment of the validity of its conclusions. We investigated the association of physician characteristics and proper assessment using logistic regression models and evaluated the interaction between the associated characteristics and overstatement. RESULTS:We found significant associations between proper assessment and post-graduate year (odds ratio [OR] = 0.67, 95% confidence interval [CI] 0.49 to 0.91, for every 10-year increase) and research experience as a primary investigator (PI; OR = 2.97, 95% CI 1.65 to 5.34). Post-graduate year and PI had significant interaction with overstatement (P = 0.015 and < 0.001, respectively). Among participants who read abstracts without an overstatement, post-graduate year was not associated with proper assessment (OR = 1.04, 95% CI 0.82 to 1.33), and PI experience was associated with lower scores of the validity (OR = 0.58, 95% CI 0.35 to 0.96). CONCLUSION:Physicians who have been in practice longer should be trained in distinguishing overstatements in abstract conclusions. Physicians with research experience might be informed that they tend to rate the validity of research lower regardless of the presence or absence of overstatements. TRIAL REGISTRATION:UMIN000026269.

Project description:A growing number of randomized controlled trials (RCTs) have investigated the therapeutic value of yoga interventions. This bibliometric analysis aimed to provide a comprehensive review of the characteristics of the totality of available randomized yoga trials.All RCTs of yoga were eligible. Medline/PubMed, Scopus, the Cochrane Library, IndMED, and the tables of content of yoga specialty journals not listed in medical databases were screened through February 2014. Bibliometric data, data on participants, and intervention were extracted and analyzed descriptively.Published between 1975 and 2014, a total of 366 papers were included, reporting 312 RCTs from 23 different countries with 22,548 participants. The median study sample size was 59 (range 8-410, interquartile range?=?31, 93). Two hundred sixty-four RCTs (84.6%) were conducted with adults, 105 (33.7%) with older adults and 31 (9.9%) with children. Eighty-four RCTs (26.9%) were conducted with healthy participants. Other trials enrolled patients with one of 63 varied medical conditions; the most common being breast cancer (17 RCTs, 5.4%), depression (14 RCTs, 4.5%), asthma (14 RCTs, 4.5%) and type 2 diabetes mellitus (13 RCTs, 4.2%). Whilst 119 RCTs (38.1%) did not define the style of yoga used, 35 RCTs (11.2%) used Hatha yoga and 30 RCTs (9.6%) yoga breathing. The remaining 128 RCTs (41.0%) used 46 varied yoga styles, with a median intervention length of 9 weeks (range 1 day to 1 year; interquartile range?=?5, 12). Two hundred and forty-four RCTs (78.2%) used yoga postures, 232 RCTs (74.4%) used breath control, 153 RCTs (49.0%) used meditation and 32 RCTs (10.3%) used philosophy lectures. One hundred and seventy-four RCTs (55.6%) compared yoga with no specific treatment; 21 varied control interventions were used in the remaining RCTs.This bibliometric analysis presents the most complete up-to-date overview on published randomized yoga trials. While the available research evidence is sparse for most conditions, there was a marked increase in published RCTs in recent years.
