Based on meta-analysis showing SMD 0.56-1.57 for cognitive status improvement. Conservative estimates due to heterogeneity across studies and varying populations (stroke, dementia, TBI). Effect sizes modest and studies show mixed quality levels.
Based on meta-analysis of 1002 stroke patients, but showed non-significant increase in death at one month. Evidence is limited and mixed. Conservative effectiveness estimates due to safety concerns.
