<\/span><\/div><\/div><\/div><\/div><\/div>Who<\/span><\/h2><\/div>One-hundred four patients in the UK were tested for SARS-CoV-2 RNA on hospital admission with symptoms suggestive of COVID-19. Of these, 57 were SARS-CoV-2 RNA negative (38 women, 66.7%; 19 men, 33.3%); 47 were SARS-CoV-2 RNA positive (27 women, 57.4%; 20 men, 42.6%). Mean age in the SARS-CoV-2 negative group was 68.5\u00b118.1 years, ranging from 25-95 years. Mean age in the SARS-CoV-2 positive group was 68.6\u00b118.7, ranging from 22-95 years.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
Things to Keep in Mind<\/span><\/h2><\/div>\n- A larger, more robust study with the analyses adjusted for ethnicity, body mas index, and comorbidities is required to validate the findings with the cohort size allowing for subgroup analyses of different populations (e.g., different ethnic groups, patients on vitamin D supplements) at varying levels of risk, which could not be considered in this study as the data were not accessible.<\/li>\n
- The vitamin D status evaluated in this study was measured within the 6 months prior to or at hospital admission. Studies with recent vitamin D measures for all patients, such as those taken at the time of hospital admission with symptoms of COVID-19 infection, would provide a more consistent dataset.<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div><\/div>
