Lifestyle Interventions for Patients With and at Risk for Type 2 Diabetes: A Systematic Review and Meta-analysis
TL;DR: The effect of multifaceted lifestyle interventions on clinically oriented outcomes across a spectrum of metabolic risk factors and abnormal glucose is unclear as discussed by the authors, and there is no evidence of reduced all-cause mortality and insufficient evidence to suggest benefit on cardiovascular and microvascular outcomes.
Journal ArticleDOI
PEDro or Cochrane to Assess the Quality of Clinical Trials? A Meta-Epidemiological Study.
Susan Armijo-Olivo,Bruno R. da Costa,Greta G. Cummings,Christine Ha,Jorge Fuentes,Humam Saltaji,Matthias Egger +6 more
TL;DR: The PeDro and Cochrane approaches lead to different sets of trials of adequate quality, and different combined treatment estimates from meta-analyses of these trials.
Journal ArticleDOI
Blinding in Physical Therapy Trials and Its Association with Treatment Effects: A Meta-epidemiological Study.
Susan Armijo-Olivo,Jorge Fuentes,Bruno R. da Costa,Humam Saltaji,Christine Ha,Greta G. Cummings +5 more
TL;DR: The lack of statistical significance between blinding and effect sizes should not be interpreted as meaning that an impact of blinding on effect size is not present in PT.
Journal ArticleDOI
Poor Reliability between Cochrane Reviewers and Blinded External Reviewers When Applying the Cochrane Risk of Bias Tool in Physical Therapy Trials
Susan Armijo-Olivo,María Angélica Ospina,Bruno R. da Costa,Matthias Egger,Humam Saltaji,Jorge Fuentes,Christine Ha,Greta G. Cummings +7 more
TL;DR: Improved guidelines to consistently apply the RoB tool and revisions to the tool for different health areas are needed after poor agreement was not only demonstrated at the trial level but also at the meta-analysis level.
Journal Article
Lifestyle Interventions for Patients With and at Risk for Type 2 Diabetes
TL;DR: Comprehensive lifestyle interventions effectively decrease the incidence of type 2 diabetes in high-risk patients and in patients who already have type 1 diabetes, there is no evidence of reduced all-cause mortality and insufficient evidence to suggest benefit on cardiovascular and microvascular outcomes.
