Purpose The aim of this study was to evaluate the changes in astigmatism after unilateral recession of horizontal rectus muscles in pediatric patients. Methods The authors retrospectively evaluated the medical history of 52 children with esotropia or exotropia, that underwent a unilateral recession strabismus surgery. The intervention group consisted of the 52 eyes that underwent strabismus surgery, and the control group consisted of the other 52 fellow unoperated eyes of the same participants. ...

Abstract Objective To introduce potential static tabular and graphical techniques for visually presenting overlap between systematic reviews (SRs) included in overviews of systematic reviews (OoSRs). Study Design and Setting The graphical approaches described include Venn and Euler diagrams, as well as matrix-based, node-link, and aggregation-based techniques. We used fundamental concepts of mathematics from set and network theory to develop our novel graphical approaches. The graphical displays...

Abstract Objective : To conduct a bibliometric analysis using a large sample of overviews of systematic reviews (OoSRs) and reveal research trends and areas of interest about these studies. Study Design and Setting : We searched MEDLINE, Scopus and Cochrane Database of Systematic Reviews from 1/1/2000 to 15/10/2020. We used Scopus meta-data and two authors recorded supplementary information independently. We summarized the data using frequencies with percentages. Results : A total of 1558 studie...

BACKGROUND Keeping up to date with the latest medical information using Web-based resources has been sparsely described, and a comprehensive up-to-date review is needed. OBJECTIVES To summarise the Web-based 'channels' that may assist the actors of the health care system (clinicians, medical researchers and students) to keep up to date with medical information. METHODS We searched PubMed and Scopus for English language articles published between January 1990 and February 2019 that investigated w...

Bullous pemphigoid (BP) patients are predominantly above 70 years of age, with limited tolerance to the side effects of the immunosuppressive drugs. Advancements in our understanding of the pathophysiology of BP have led to the development of molecules which target specific pathways involved in induction and perpetuation of disease. Objectives and methods Patients with BP Disease Area Index above 60 and less than 100 were split into two groups - one with high and the other with normal levels of ...

Abstract Gene promoter methylation is a common epigenetic event, taking place in the early phase of tumorigenesis, which has a great potential as a diagnostic and prognostic cancer biomarker. In this umbrella review, we provide an overview on the association between gene-promoter methylation of protein-coding genes and cancer risk based on currently available meta-analyses data on gene promoter methylation. We searched MEDLINE via PubMed and the Cochrane Database of Systematic Reviews for meta-a...

Abstract Objective An overview of systematic reviews (OoSRs) is a study designed to offer a broad view of evidence from existing systematic reviews (SRs). The abstract is an important part of an OoSRs as it can determine whether reading the full text is of interest. The aim of this article is to offer guidelines to promote transparent and sufficient reporting in abstracts of OoSRs of health care interventions. Study Design and Setting The items were developed by combining key features from abstr...

The goal of this chapter is to provide an overview of essential biostatistical methods available to landmarks trials that investigate hypertension. We begin with an introduction to the basic types of variables and then demonstrate methods for summarizing, visualizing, and understanding data. The chapter continues with basic principles in the context of hypothesis testing and interpretation of effect sizes, confidence intervals and p-values. We also describe the processes of selecting the appropr...

Abstract Background and aims Creatine is a supplement used by sportsmen to increase athletic performance by improving energy supply to muscle tissues. It is also an essential brain compound and some hypothesize that it aids cognition by improving energy supply and neuroprotection. The aim of this systematic review is to investigate the effects of oral creatine administration on cognitive function in healthy individuals. Methods A search of multiple electronic databases was performed for the iden...
