In an observational study, among 86 patients, 21 received Tocilizumab during the hospital stay. Both the Cox model and treatment effects models showed short-term survival benefit. There was an associated 75% reduction in the risk of inpatient death when treated (HR 0.25; 95% CI 0.07-0.90) in the Cox model. This association was confirmed in the treatment effects model where we found a 52.7% reduced risk of dying while hospitalized compared to those not treated (RR 0.472; 95% CI 0.449-0.497). In both models, we show short-term survival benefit in patients with severe COVID-19 illness.
