 Fifty 50 patients were chosen as a convenient sample size, based on enrollments from all of the participating hospitals, with recruitment accomplished in a reasonable timeframe of 2 years. About 65 of unselected patients with ICH that is, not stratified by baseline predicted risk have a documented 30- day composite outcome of death or dependency under medical management. Reviews of other types of minimallyinvasive ICH surgeries provide evidence of significantly improved outcomes meta-analysis odds ratio 0.54 0.39, 0.76. An odds ratio of 0.54 indicates a reduction in risk from 65 to about 50 15 absolute reduction.
