BACKGROUND: Systematic reviews represent the highest form of evidence in the current hierarchy of evidence-based dentistry. Critical analysis of published systematic reviews may help to analyze their strengths and weaknesses and to identify areas that need future improvement. The aim of this overview is to determine an…

OBJECTIVE: Advances from health research are not well applied giving rise to over- and underuse of resources and inferior care. Knowledge translation (KT), actions and processes of getting research findings used in practice, can improve research application. The KT literature is difficult to find because of nonstandard…

Traditional Chinese medicine (TCM) is currently considered a complementary or alternative medical system in most Western countries and has been increasingly accepted worldwide. More and more clinical trials on TCM have been conducted internationally, and scientists worldwide are becoming increasingly interested in the…

AIMS: To identify high-quality systematic reviews for all interventions in three defined areas of liaison ps…

OBJECTIVES: The aim of the Consensus on Health Economic Criteria (CHEC) project is to develop a criteria list for assessment of the methodological quality of economic evaluations in systematic reviews. The criteria list resulting from this CHEC project should be regarded as a minimum standard. METHODS: The criteria li…

The available data unambiguously support the beneficial, short-term fetal effects of antenatal corticosteroids in women at risk for preterm delivery. There are still several incompletely addressed questions, including the use of corticosteroids in women with preterm premature rupture of membranes, the optimal corticost…

The purpose of this paper is to provide an overview of the current literature regarding the psychosocial well-being of children with chronic disease, their parents and siblings. METHODS: Elect…

There has been increasing concern about compromised integrity in randomized controlled trials (RCTs) because it undermines the authority of this top-level evidence-generating method and puts patients at risk. Compromised RCTs also jeopardize the validity of systematic reviews and meta-analyses when they are included. T…

OBJECTIVE: To provide health care providers, patients, and the general public with a responsible assessment of currently available data regarding the diagnosis and management of dental caries throughout life.

The relocation and reconstruction of health care resources and systems during the coronavirus disease 2019 (COVID-19) pandemic may have affected cancer care. An umbrella review was undertaken to summarize the findings from systematic reviews on impact of the COVID-19 pandemic on cancer treatment modification, delays, a…

BACKGROUND: Oral leukoplakia (OL) represents the most common oral potentially malignant disorder globally, with highly variable reported malignant transformation (MT) rates creating challenges for evidence-based clinical management. OBJECTIVE: To systematically synthesize evidence on MT prevalence in OL and evaluate p…

OBJECTIVES: To assess and synthesize the effect size and quality of the literature on the placebo and nocebo effects on motor performance and motor-related perceptive responses.
