Official titleEFFECTIVENESS AND SAFETY OF TOCILIZUMAB IN INTERSTITIAL PNEUMONIA WITH SERIOUS RESPIRATORY FAILURE SECONDARY TO SARS-COV-2 INFECTION (COVID-19): COHORT STUDY
Study title acronymTOCICOV-19
Study typeObservational study
Brief description of the studyThis is a prospective multi-center cohort post-authorization drug study. A percentage of the patients included in this cohort will be recruited retrospectively, therefore, the overall study design is ambispective.
From the patients admitted to the hospital for COVID-19 with a diagnosis of interstitial pneumonia with severe respiratory failure, two cohorts will be selected based on their exposure (or not) to treatment with tocilizumab.
The study will be carried out under real healthcare conditions.
Data will be collected from days 1, 3, 7, 15 and 28 post inclusion (or treatment)

15. Data analysis plan
Please provide a brief summary of the analysis method
490/5000
The incidence in exposed (cohort treated with tocilizumab) and in non-exposed (untreated cohort) will be calculated for each of the effectiveness variables. From these, the measures of association relative risk (RR), absolute risk reduction (RAR) and relative risk reduction (RRR) will be calculated for each of the variables, with their 95% CIs. Additionally, the odds ratios (OR) will be calculated.
The RR adjusted for comorbidities and prognostic factors will be estimated.
