用统计学方法来看伊麦妞医生的羟氯喹疗法 What is the probability of Dr. Stella Immanuel’s claim of no death in the 350 Covid-19 Patients? 
Dr. Stella Immanuel claimed that she treated 350 COVID-19 patients with HCQ. None of them died.
Based on the US COVID-19 death rate of 3.3%, the probability that none of Dr. Stella’s 350 patients died is 96.7%^350=0.00079%. The estimated death rate is 0% with 95% CI (0%, 1%). Using all US COVID-19 patients as a control group (as of Aug 5, 2020, there are 4,882,908 patients and 159,629 deaths) and Dr. Stella Immanuel’s patients as a treatment group, the p value of Fisher’s exact test is <0.0001. Dr. Immanuel’s treatment is statistically significantly better. There should be electronic medical records for Dr. Stella Immanuel’s patients. We should be able to verify her claim. If she can provide medical records with her patients’ age, medical history, etc, we can provide a better assessment. Why Facebook, YouTube and Twitter removed Dr. Immanuel’s video about her method of treating Covid-19 patients?
