By adopting more appropriate statistical methods to appraise data from a previously published randomized controlled trial, the statistical and clinical significance of an intervention on the 18-month neurodevelopmental outcome of infants with suspected brain injury is evaluated. The intervention group (n = 32) receives extensive, individualized cognitive/sensorimotor stimulation by public health nurses while the control group (n = 30) receives standard follow-up care. At 18 months, 43 infants remain in the study (22 intervention and 21 control). The results indicate that there is a significant statistical change within groups and a clinical significance whereby more infants in the intervention group improve in mental, motor, and neurological functioning at 18 months compared to the control group. The benefits of looking at clinical significance from a meaningful aspect for practitioners are emphasized.

UI	MeSH Term	Description	Entries
D007223	Infant	A child between 1 and 23 months of age.	Infants
D001930	Brain Injuries	Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.

D016022	Case-Control Studies	Comparisons that start with the identification of persons with the disease or outcome of interest and a control (comparison, referent) group without the disease or outcome of interest. The relationship of an attribute is examined by comparing both groups with regard to the frequency or levels of outcome over time.

D017063	Outcome Assessment, Health Care	Research aimed at assessing the quality and effectiveness of health care as measured by the attainment of a specified end result or outcome. Measures include parameters such as improved health, lowered morbidity or mortality, and improvement of abnormal states (such as elevated blood pressure).
