Dataset Information

Full-text publication rate of abstracts presented at the Japan Primary Care Association Annual Meetings (2010-2012): a retrospective observational study.

ABSTRACT:

Objective

To determine the publication rate of abstracts presented at the Japan Primary Care Association Annual Meetings and the factors associated with publication.

Design

A retrospective observational study.

Participants

All abstracts presented at the Japan Primary Care Association Annual Meetings (2010-2012).

Main outcome measures

Publication rates were determined by searching the MEDLINE database for full-text articles published by September 2017. Data on presentation format (oral vs poster), affiliation of the first author, number of authors, number of involved institutions, journal of publication and publication date were abstracted.

Results

Of the 1003 abstracts evaluated, 38 (3.8%, 95% CI 2.6% to 5.0%) were subsequently published in peer-reviewed journals indexed in the MEDLINE database. The median time to publication was 15.5 months (IQR, 9.3-29.3 months). More than 95% of published abstracts were published within 4 years. The publications appeared in 23 different journals (21 English-language journals and two Japanese-language journals). Based on univariate analysis using binary logistic regression, publication was more frequent for oral presentations (7.3%vs2.0% for poster presentations; OR 3.91,95% CI 1.98 to 7.75), and for first authors affiliated with university-associated institutions (6.4%vs2.4% for first authors affiliated with non-university-associated institutions; OR 2.75,95% CI 1.42 to 5.30). Based on multivariate analysis, oral presentation and first author affiliation with a university-associated institution were still the only independent predictive factors for publication (adjusted OR 3.50(95% CI 1.72 to 7.12) and adjusted OR 2.35(95% CI 1.19 to 4.63), respectively). Even among 151 abstracts presented orally by first authors affiliated with a university-associated institution, only 18 abstracts (11.9%) were subsequently published in peer-reviewed journals.

Conclusions

The publication rate of abstracts presented at the Japan Primary Care Association Annual Meetings was extremely low. Further studies are warranted to investigate the barriers to publication among investigators who participate in conferences where the publication rate is extremely low.

Project description:ObjectivesTo evaluate the reporting quality of randomised controlled trial (RCT) abstracts presented at a leading international conference in sleep medicine (the SLEEP Annual Meeting), and to investigate the association between potential predictors and the reporting quality of trial abstracts in this field.DesignCross-sectional, research on research study.MethodsA handsearch of the 2016-2018 SLEEP Annual Meeting abstract books was carried out to identify abstracts describing RCTs. Quality of reporting was assessed with the original 17-item CONSORT for Abstracts checklist. Univariable and multivariable linear regression analyses were performed to identify significant predictors of reporting quality. In addition, risk ratios were used to analyse the adequate reporting rate of each quality item by type of intervention and funding status.Primary and secondary outcome measuresThe overall quality score (OQS, range 0-17) in accordance with the CONSORT for Abstracts checklist (primary outcome), and the adequate reporting rate of each checklist item (secondary outcome).ResultsA total of 176 RCT abstracts were included and assessed. The mean OQS was 5.53 (95% CI 5.30 to 5.76). Only three quality items (objective, conclusions and funding) were adequately reported in most abstracts (>75%). None of the abstracts adequately reported authors, randomisation or outcome in the results section. According to the multivariable analysis, pharmacological interventions (p=0.018) and funding from the industry (p=0.025) were significantly associated with better reporting quality.ConclusionsThe reporting quality of RCT abstracts presented at SLEEP Annual Meetings was suboptimal. Pharmacological intervention and funding from industry were significant predictors of better reporting quality. Joint efforts by authors and conference committees are needed to enhance the reporting quality of RCT abstracts presented at sleep medicine conferences, and thereby reduce relevant research waste in this field.
