Systematic reviews and meta-analyses form a secondary research methodology that identifies and critically appraises all the relevant studies that are available in various databases to answer a particular research question in an unbiased and systematic manner. In the pyramid of level of evidence, the systematic review of high-quality studies is placed at the highest hierarchy position. Meta-analysis is the statistical analysis of the systematic review that provides pooled estimates of the effect of individual studies in the systematic review, but sometimes a meta-analysis may not always be possible. This article elaborates the key steps to conduct a high-quality systematic review and meta-analysis in the field of radiology and intervention radiology, which will help the readers to design and conduct them along with to understand and interpret this secondary research.

Parental experiences of caring for their preschool children after declining vaccines: a qualitative systematic review.
JBI Evid Synth
January 2025
University of Alberta, Edmonton, AB, Canada.
Objective: This review synthesizes qualitative research about the experiences of parental caregivers enhancing their children's health after making the decision to not vaccinate their preschool children. This review aims to help health care providers understand the parental work involved in caring for under-vaccinated or unvaccinated children.
Introduction: Much of the current qualitative research literature about parents who are vaccine-hesitant or who decide not to vaccinate their children focuses on parental perceptions about the safety and efficacy of vaccines and decision-making.
Experiences of African women who migrate to a developed country and encounter intimate partner violence: a systematic review of qualitative evidence.
JBI Evid Synth
January 2025
School of Nursing and Midwifery, University of Newcastle, Newcastle, New South Wales, Australia.
Objective: The objective of this review was to synthesize the available evidence on the experiences of African women who migrated to a developed country and encountered intimate partner violence (IPV).
Introduction: IPV is a significant public health issue, and migrant women living in developed countries are particularly vulnerable to IPV, experiencing disproportionately higher rates of IPV. Understanding the experiences of these women can inform health policy and decision-making in clinical practice to minimize IPV.
Minimally Invasive vs Open Surgery for Thoracolumbar Fractures Treatment: A Meta-analysis of Randomized Controlled Trials and Prospective Studies.
Spine (Phila Pa 1976)
January 2025
Department of Orthopedic Surgery, Hotel Dieu de France Hospital, Beirut, LEBANON.
Study Design: Meta-Analysis.
Objective: The purpose of this systematic review and meta-analysis was to pool the available data comparing MIS to open surgery for thoracolumbar fractures and provide a more comprehensive assessment on this topic.
Background: There remains a debate over whether minimally invasive surgery (MIS) or open fixation provides superior outcomes for patients with thoracolumbar fractures.
Unraveling the transcriptomic landscape of brain vascular cells in dementia: A systematic review.
Alzheimers Dement
January 2025
UK Dementia Research Institute at the University of Edinburgh, Edinburgh, UK.
Introduction: Cerebrovascular dysfunction plays a critical role in the pathogenesis of dementia and related neurodegenerative disorders. Recent omics-driven research has revealed associations between vascular abnormalities and transcriptomic alterations in brain vascular cells, particularly endothelial cells (ECs) and pericytes (PCs). However, the impact of these molecular changes on dementia remains unclear.

Heat stress has been proven to cause negative effects on livestock leading to lower productivity and economic value. Understanding how heat stress manifests within an animal's body is the first step in devising a heat stress mitigation strategy; transcriptomic studies are one of the methods used. Here, using a systematic literature review methodology, we examine the recent decade of transcriptomics' application to the study of livestock adaptation.
