Low blood sodium increases risk and severity of COVID-19: a systematic review, meta-analysis and retrospective cohort study	2020-05-22		.txt	text/plain	3903	200	47	title: Low blood sodium increases risk and severity of COVID-19: a systematic review, meta-analysis and retrospective cohort study Through a systematic review, meta-analysis and retrospective cohort study, we found that the low blood sodium population may significantly increase the risk and severity of SARS-CoV-2 infection. In this study, we aimed to find a key risk factor for SARS-CoV-2 epidemic by investigating the relationship between the blood sodium concentration and the severity of patients with COVID-19 through a systematic reviews, meta-analysis and retrospective cohort study. For the systematic review and meta-analysis, median or mean values of serum sodium, chloride and potassium concentrations from each report were considered as an independent variable for statistical analysis, and an unpaired t-test was used to compare the differences between the groups related to the severity of disease. In this study, we found that the patients infected by SARS-CoV-2 on admission have presented the low blood sodium levels (hyponatremia) that were related to the disease severity.	./cache/cord-279158-dsnniuo6.txt	./txt/cord-279158-dsnniuo6.txt
