“…Unfortunately, in dentistry 4,5,8 and other biomedical sciences, 6 many published research articles would be considered to have a low LoE. However, LoEs provide an incomplete picture since studies that have the same LoE nominally, may differ in essential methodological aspects (e.g.…”

“…4,5,8 An additional advantage of the MINCIR scale is that it enables one to perform systematic reviews of clinical trials, cohort studies, case-control, and case series studies. 11 The MINCIR scale has been used to assess surgical studies, 6 including studies in the areas of oral and maxillofacial surgery, 8 and has demonstrated psychometric properties. 12 However, these may vary depending on the study population; so it is necessary to have validation procedures to assure adequacy.…”

“…Adopting the parameters of a 95% confidence level, 1-point accuracy, and a standard deviation of 4.95 points, 6 we determined that the required sample size was 94, which we rounded to 100. Given that MQ would be expected to correlate with impact factor, as in surgical studies, 6 a stratified sampling method was used. We selected one journal per quartile (Q1 to Q4) of the 2012 Journal Citation Report.…”

“…MQ assessments cannot replace LoE, or other, evaluations but can complement traditional quality evaluations of clinical research. 6 Furthermore, instruments that show psychometric properties are needed to perform any evaluation. The aim of this study was to determine the validity and reliability of the MINCIR scale for determining MQ assessments of dental studies published in 2012 in journals indexed in an Institute for Scientific Information (ISI) database.…”

Abstract:The clinical paradigm of evidence-based medicine requires a foundation of good quality research upon which clinical and epidemiological decisions can be based. Several instruments have been designed to assess research quality and validated, though most have limitations. The MINCIR scale was designed to determine the methodological quality (MQ) of clinical research, its psychometric properties for dental research involving large-scale evaluations have not yet been determined. The aim of this study was to determine the validity and reliability of the MIN-CIR scale for assessment of the MQ of dental therapy studies published in journals indexed in Institute for Scientific Information (ISI) databases. A validation study was performed on a sample of 99 articles from four representative ISI dental journals. Criterion validity was determined in relation to level of evidence (LoE) classification as described by the Oxford Center for Evidence-Based Medicine (OCEBM) ranking system, reliability was determined by calculation of intra-class correlation coefficient (ICC) values, and internal consistency was determined by calculation of Cronbach's alpha. Very good inter-observer reliability (ICC = 0.93), excellent temporal stability (ICC = 0.97), good internal consistency (Cronbach's alpha = 0.77), and a strong (inverse) correlation with OCEBM LoEs (-0.807; p < .0001) were obtained. These results indicate that the MINCIR scale has adequate psychometric properties and therefore is a valid option for use in the assessment of MQ in dental therapy research articles.

Laparoscopic right colectomy: a systematic review and meta-analysis of observational studies comparing two types of anastomosis

2013

Because of its technical difficulty, totally laparoscopic right colectomy with intracorporeal anastomosis is performed only by a small number of surgeons and most of them use a laparoscopic-assisted technique with extracorporeal anastomosis. This systematic review aims to evaluate differences in outcomes of patients undergoing right laparoscopic colectomy, either with intracorporeal or extracorporeal anastomosis. Electronic databases were searched for studies published between 1991 and 2012. Randomized controlled trials and case-control studies comparing intracorporeal to extracorporeal anastomosis in laparoscopic right colectomy were included in the systematic review. Meta-analytical models were used to evaluate anastomotic leak rate and short-term overall morbidity. Defined primary outcomes of interest were operating time, conversion rate, return of bowel function, anastomotic leak rate, and length of hospital stay. Randomized controlled trials were not found, confirming the paucity of the literature on this topic. Six case-control studies were identified involving 484 patients undergoing right laparoscopic colectomy, 272 with intracorporeal and 212 with extracorporeal anastomosis. Best outcomes seem to be associated with totally laparoscopic right colectomy with intracorporeal anastomosis, especially in terms of return of bowel function, length of hospital stay, and cosmetic results. However, our meta-analysis did not show a significant difference between the two techniques in terms of anastomotic leak rate (OR 0.98; 95 % CI 0.30-3.15) or for short-term overall morbidity (OR 0.68; 95 % CI 0.41-1.12). Comparative analysis of outcomes is in favor of intracorporeal anastomosis. However, the meta-analysis results do not allow us to draw definitive conclusions. Further prospective randomized trials are necessary to confirm our findings.

PURPOSE:This study was designed to analyze the characteristics and the quality of reporting of randomized, controlled trials published during the last ten years on fecal incontinence.METHODS: An electronic search for all randomized, controlled trials on fecal incontinence was undertaken by using the MEDLINE database via PubMed. The data collected were divided into general data, characteristics of reporting, methodology quality assessment using the Jadad scale and a validated methodology quality score (MINCIR score), evaluation of the items published in the CONSORT statement, and the journal impact factor.

What Is the Methodologic Quality of Human Therapy Studies in ISI Surgical Publications?

Abstract: The methodologic quality of therapy articles published in the journals analyzed is low; however, statistical significance was determined between them. Association was observed between methodologic quality and origin, but not with subject matter.
