n = 83, but sure.

  Actually n=2*83=166

  29 deaths or ventilators in the control group of 83, 14 in the test group of 83. So, 43 total in the combined 166 subjects. That suggests that if the drug has no effect, there is about a 26% chance that a subject will die or need a ventilator (which is not surprising given that all the subjects were elderly). If the drug has no effect and the death/ventilator probability is 0.26, then the probability that the control group of 83 would have >= 29 deaths/ventilators is 0.044. The probability that the test group would have <= 14 deaths/ventilators is 0.034. That seems good enough to warrant further research.
