A secondary outcome, significant improvement, was defined as much better or very much better.
It will be used to classify participants with a successful outcome, defined as 'moderately better' or "a great deal better' across each indicator.
For the purposes of the summary data, best-corrected VA was described (defined as the better of PVA or pinhole-corrected VA in the better eye).
A great teacher (defined as one better than 84 percent of peers) for a single year between fourth and eighth grades resulted in students earning almost 1 percent more at age 28.
But new products tend to be more efficient than old ones (which is one reason why rich countries' energy efficiency increases by around 2% a year); and if some of that efficiency is used to cut fuel consumption, they can be defined as environmentally better.
'Success' on global perceived effect being defined as 'much better' or 'better' and all other categories as 'failure'failure
Median FEV1 % predicted was 73 and this was taken as a cut off between groups defined as having better or worse lung function.
Sample size is based on the ability to detect a 25% difference in the success rate (defined as "much better" or "completely recovered" on a 6-point Likert-scale) between the groups at three months.
More participants in the active group reported a successful outcome (defined as "much better"), although the difference was not statistically significant: 42% (24/57) of active participants and 30% (18/61) of placebo participants (relative risk 1.43, 0.87 to 2.34).
More participants in the active group reported an overall successful outcome (defined as "much better"), although the difference was not statistically significant: 42% of active participants and 30% of placebo participants (relative risk 1.43, 95% confidence interval 0.87 to 2.34) (table 4).
