ObjectivesTo analyse the relationship between demographic characteristics, reporting quality and final publication rate of conference abstracts of prosthodontic randomised-controlled trials (RCTs) presented at International Association for Dental Research (IADR) general sessions (2002–2015).DesignA cross-sectional study on conference abstracts.MethodsConference abstracts of prosthodontic RCTs presented at IADR general sessions (2002–2015) were obtained. Literature search was performed in multiple databases to confirm the final publication status of conference abstracts. Two investigators independently extracted the data including conference date, origin, presentation type, exact p value, number of centres, institution type, overall conclusion, subspecialty, publication time and journal. The reporting quality of abstracts was assessed by two investigators according to the Consolidated Standards of Reporting Trials statement. The relationship between demographic characteristics, reporting quality and final publication was analysed by χ2test.Setting, participants and interventionsNot applicable.Primary and secondary outcome measuresFinal publication rate, demographic characteristics and reporting quality of conference abstracts of prosthodontic RCTs presented at IADR general sessions (2002–2015).ResultsOf the 340 prosthodontic RCT abstracts, 43.24% were published. The mean time to final publication was 22.86 months. Europe contributed the most number of abstracts but Asia and Australia had the highest publication rate. Oral presentation, multicentre trial and complete denture and overdenture subspecialty were associated with a higher publication rate. Reporting quality of eligibility criteria of participants, random assignment and primary outcome results for each group correlated with a higher final publication rate.ConclusionsOver half of conference abstracts of prosthodontic RCTs presented at IADR general sessions (2002–2015) were unpublished. Oral presentation and multiple centres were associated with higher publication rates. Abstracts’ reporting quality addressing participant recruitment, assignment and primary results correlated with trials’ validity and applicability. Conference attendees may refer to this research to identify valid and applicable prosthodontic trials but should treat and apply results cautiously.

ObjectivesTo assess the value of pilot and feasibility studies to randomised controlled trials (RCTs) funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme. To explore the methodological components of pilot/feasibility studies and how they inform full RCTs.Study designCross-sectional study.SettingBoth groups included NIHR HTA programme funded studies in the period 1 January 2010–31 December 2014 (decision date). Group 1: stand-alone pilot/feasibility studies published in the HTA Journal or accepted for publication. Group 2: all funded RCT applications funded by the HTA programme, including reference to an internal and/or external pilot/feasibility study. The methodological components were assessed using an adapted framework from a previous study.Main outcome measuresThe proportion of stand-alone pilot and feasibility studies which recommended proceeding to full trial and what study elements were assessed. The proportion of ‘HTA funded’ trials which used internal and external pilot and feasibility studies to inform the design of the trial.ResultsGroup 1 identified 15 stand-alone pilot/feasibility studies. Study elements most commonly assessed weretesting recruitment(100% in both groups),feasibility(83%, 100%) andsuggestions for further study/investigation(83%, 100%). Group 2 identified 161 ‘HTA funded’ applications: 59 cited an external pilot/feasibility study wheretesting recruitment(50%, 73%) andfeasibility(42%, 73%) were the most commonly reported study elements: 92 reported an internal pilot/feasibility study wheretesting recruitment(93%, 100%) andfeasibility(44%, 92%) were the most common study elements reported.Conclusions‘HTA funded’ research which includes pilot and feasibility studies assesses a variety of study elements. Pilot and feasibility studies serve an important role when determining the most appropriate trial design. However, how they are reported and in what context requires caution when interpreting the findings and delivering a definitive trial.

Background. Psoriatic arthritis (PsA) results in an increased burden of psoriasis and impairs both quality of life and an individual’s functional capacity. The relationship between nail involvement and PsA in psoriasis is not fully characterized. Aim. To evaluate the frequency and characteristics of nail involvement in psoriatic patients and to assess the relationship with joint involvement. Methods. A total of 197 patients with moderate-to-severe psoriasis were consecutively invited to participate in this cross-sectional study. The patients are divided into two groups: those with and those without psoriatic arthritis. Results. 69.5% of psoriatic (137 out of 197) patients had nail involvement. The most common nail abnormality was onycholysis, followed by pitting and oil droplet changes. Nail involvement was more common in patients with psoriatic arthritis (82.1% versus 57.8%, p=0.001). Conclusion. Nail involvement is commonly associated with PsA. Onycholysis, splinter hemorrhage, and oil drop were significantly more common in the PsA group as opposed to patients with just skin findings. In general, psoriatic patients with arthritis had more severe disease.
