Retrospective Analysis of Hydroxychloroquine in 84


                   Hospitalized Patients With COVID-19: Study Arm


               There are many studies on hydroxychloroquine. I just want to put up one study, the
               French study that said that “hydroxychloroquine is a wonder drug and nobody should

               live without the drug”.  It is actually a retrospective cohort study where they looked at
               all their patients who were on hydroxychloroquine versus those who are not on
               hydroxychloroquine [9]. They tried to balance all the relevant confounding factors like

               age, gender, comorbidities, BMI>30kg/m , 3rd trimester of pregnancy, treatment with
                                                            2
               angiotensin-converting enzyme (ACE) inhibitor or an angiotensin receptor blocker
               (ARB), times since symptom onset and severity of disease. These are all the important

               parameters which they have adjusted for.

               by Mahévas et al.



                   Hydroxychloroquine was given to patients who were around Day 8 of illness. Many
               of them actually require oxygen, SpO2 of 92%.
