You are on the DSMB of a double-blind clinical trial of a two-arm pharmaceutical intervention study with a time-to-event outcome. A DSMB meeting will occur after the first third of the participants are enrolled. Briefly describe two data summaries you would expect to be reported on in the open session of a DSMB meeting, and give a brief rationale for why the DSMB would want to see those summaries

The drug ancrod was tested in a double-blind clinical trial in which stroke patients were randomly assigned to receive either ancrod or a placebo. One of the response variables in the study was whether or not the subjects experienced intracranial hemorrhaging. Of the 84 patients who received ancrod, 13 hemorrhaged. Of the 77 patients who received the placebo, only three hemorrhaged. a.Is there a significant difference in hemorrhaging rates between treatments? Show your work and include all steps for full...
