We applied statistical analysis (Pearson chi-square) to assess the differences in outcomes for patients receiving different interventions.
When they studied the variations between schools and systems serving similar students in different parts of the country, they found wide differences in outcomes.
This way any differences in outcomes (heart attacks and strokes) can be reliably attributed to sodium consumption.
For example, two earlier controlled trials, each involving only about 100 men with early stage cancer, showed no differences in outcomes.
But Cappelli points out that for parents and students the average figures may not mean much, because they disguise enormous differences in outcomes from school to school.
However, differences in outcomes between centers have not been evaluated.
This study is limited by the exclusion of transferred patients and potentially underestimates differences in outcomes.
Differences in outcomes were evaluated using t test and Chi-square test.
We evaluated the differences in outcomes among children with blunt pancreatic injuries managed operatively and nonoperatively.
There were no other statistically significant differences in outcomes between the two prostheses.
We hypothesized that triage patterns would be associated with differences in outcomes.
