Retrospective 477 COVID+ public transportation workers in Turkey, showing lower risk of hospitalization with vitamin C use in unadjusted results.
This is the 55th of 73 COVID-19 controlled studies for vitamin C, which collectively show efficacy with p=0.00000002 (1 in 50 million).
21 studies are RCTs, which show efficacy with p=0.0012.
This study is excluded in the after exclusion results of meta analysis: unadjusted results with no group details.
Study covers vitamin D and vitamin C.

BACKGROUND: In metropolitans, where public transportation is used extensively, bus drivers are one of the occupational groups with a high risk of contracting COVID-19. OBJECTIVE: This study aimed to assess the difference between the clinical status of a group of bus drivers and field officers with COVID-19 on public transportation lines in Istanbul. METHODS: The study was conducted with 477 male volunteer participants. COVID-19 was confirmed through a positive nasopharyngeal culture sample using the real-time PCR test. Demographic information, biochemical parameters, clinical status, and the use of nutritional supplements were compared between those who recovered from COVID-19 at home or in the hospital. RESULTS: The body mass indexes (BMI) of 83.9% of individuals was above normal and 75.4% were treated for the disease at home. There were significant differences in terms of age, BMI, weight loss, smoking, use of nutritional supplements, blood glucose levels and vitamin B 12 values. However, there was no significant difference between the types of nutritional supplements used or other biochemical parameters. CONCLUSION: It was determined that those who survived the disease at home were younger and had a lower BMI. It is important for both individuals and for general public health to create healthy working environments, especially for bus drivers, who have a high risk of COVID-19 contamination and transmission due to their long exposure time.
