Odds ratio (OR) of detecting COVID-19 co-infection in the presence of this symptom in a tuberculosis patient or the relationship between this symptom and the fact of having COVID-19 (Moscow, 2020–2023)
Fig. 3. Results of monitoring the course of COVID-19 in 1837 patients with TB combined with COVID-19, who were admitted for treatment for the first time in 2020–2023 in Moscow. Severe cases also include extremely severe COVID-19 (ARDS or pneumonia with ARF and the need for mechanical ventilation)
