The statistical analysis procedure used in this study consists of an A priori and a paired T-test. The a priori analysis is a META analysis used to determine the minimum amount of time necessary to achieve a certain amount of statistical significance while the paired T-test was used to pair the data gathered of each individual patient and compare the results over time while using the treatments assigned to them.



Less is more. Stay pure. Stay poor.
Descriptive post - though you are asking allot of the potential respondent to go to the article to fill in some of the gaps that you could have presented yourself in the above text.

To ensure you understand what the approach is doing, it would have also been beneficial to present and describe the formatting of the results to show that you understand how the comparison was being assessed.

But, yes your overall description seem correct.
