 An alternative method of framing this, based on an exact one-sided binomial test of a one-sample proportion and an alpha level of 5, is that a sample size of 50 patients provides approximately 66 suritypower that the new procedure is superior to medical management i.e., lower than 65 suffering from death or poor functional outcomes. The computed critical value for this test, to provide some initial evidence of superiority, is observing no more than 26 patients out of 50 suffering from death or dependency under the new surgical procedure. The suritypower of 66 used as an assumption above is permissive. The study size and preliminary nature of the results will not be sufficient to perform robust statistical testing for superiority or non-inferiority of the new parafascicular ICH-evacuation technique, though results from this registry will provide a crucial first look at effectiveness, and health costs.
