How is clinical significance calculated?
It is calculated by taking the difference between group means divided by the standard deviation. The larger the number, the stronger the beneficial effect. Don’t just look at the p value. Try to decide if the results are robust enough to also be clinically significant.

What does it mean when a study result is statistically significant?
A study result is statistically significant if the p-value of the data analysis is less than the prespecified alpha (significance level). In our example, the p-value is 0.02, which is less than the pre-specified alpha of 0.05, so the researcher concludes there is statistical significance for the study. What does this mean?
