medrxiv Subject Collection: Infectious Diseases: A systematic review and meta-analysis protocol on the association of malaria in pregnancy and adverse birth outcomes


Listen to this article
Abstract: Introduction: Malaria in pregnancy contributes to significant adverse birth outcomes. This study is aimed to quantify the relationship between malaria in pregnancy and occurrence of adverse birth outcomes, including preterm delivery, low birth weight, small for gestational age, miscarriages, and stillbirth. Methods and analysis: Observational studies and Randomised controlled trials reporting data on selected birth outcomes separately for pregnancies, with or without malaria will be included. We will search for studies over various information sources and data extraction will be done from included studies. Pooled odds ratio (OR) will be calculated for each birth outcomes using fixed effect model or random effects models, based on the level of heterogeneity. Forest plot will be prepared with effect size (with 95 percent confidence interval) of each study and pooled effect size. The methodological quality will be assessed for included observational studies using the Newcastle-Ottawa scale (NOS). Cochrane Risk of Bias tool will be used to evaluate bias in randomised controlled trials. For publication bias, funnel plot will be prepared and assessed for asymmetry, along with Egger’s test. Discussion: This study will provide an estimate of the risk of adverse birth outcomes in pregnancies with malaria. Results of this study will contribute towards planning effective service delivery in areas with a higher risk of malaria transmission. Ethics and dissemination: The current study is a review of published literature, and it does not require ethical committee approval. Results of this review will be published in a peer-reviewed journal. PROSPERO registration number: CRD42020153009
