Methods This meta-analysis was performed in adherence to the PRISMA statement. Two reviewers systematically searched PubMed, EMBASE and Web of Science, using predefined inclusion and exclusion criteria. Only studies using invasive coronary angiography combined with FFR for assessment of intermediate coronary stenoses were included. The QUADAS-2 criteria were applied for quality appraisal. A ran...

Aim To assess the diagnostic performance of lateral radiograph of the neck for supraglottitis in adults and children. Methods Electronic database searches (including PubMed, EMBASE, CINAHL, Web of Science, and WHO International Clinical Trials Registry Platform) were carried out through July 2014. Citations of included studies and recent narrative reviews were searched. Studies that compared ...

BACKGROUND Atrial fibrillation (AF) affects around 2% of the population and early detection is beneficial, allowing patients to begin potentially life-saving anticoagulant therapies. Blood pressure (BP) monitors may offer an opportunity to screen for AF. AIM To identify and appraise studies which report the diagnostic accuracy of automated BP monitors used for opportunistic AF detection. ME...

•The diagnostic performance of abbreviated MRI matches standard breast MRI. •Few studies investigated screening populations alone. mean examination time is significantly reduced. protocols reported are very varied. AIM To undertake a meta-analysis the (ABB) magnetic resonance imaging (MRI) and full protocol (FDP-MRI) in cancer. MATERIALS AND METHODS This was performed using Preferred Reporting ...

Objective: To determine the diagnostic accuracy of ultrasound to detect deep--vein thrombosis in pregnant patients. Method: We searched Pubmed, LILACS, Scopus, Google Scholar and System for Information on Grey Literature from inception to April 2016. The reference lists of the included studies were analyzed. Original articles from accuracy studies that analyzed ultrasonography to diagnose de...

BACKGROUND Low disease prevalence and lack of uniform reference standards in primary care induce methodological challenges for investigating the diagnostic accuracy of a test. We present a study design that copes with these methodological challenges and discuss the methodological implications of our choices, using a quality assessment tool for diagnostic accuracy studies (QUADAS-2). DESIGN Th...

BACKGROUND Both pregnant women and providers of obstetric care are aware of the rapid advances in noninvasive prenatal diagnosis (NIPD) of fetal trisomies, and appear to look forward to its clinical introduction. OBJECTIVES To review and critically assess the published literature on diagnostic accuracy of NIPD using cell-free fetal DNA or RNA in maternal blood to detect fetal trisomy 21. ME...

Many techniques have been introduced to enable quantification of tissue perfusion in patients with peripheral arterial disease (PAD). Currently, none these is widely used analyse real time changes during endovascular or surgical revascularisation procedures. The aim this systematic review was provide an up date overview the peri-procedural applicability currently available techniques, diagnosti...
