This specification ensures that a power greater 90% is achieved if both treatments have a worthwhile effect of 35%.
The pain must be of sufficient intensity (greater than 2 out of 10 on a numerical pain scale) to permit a clinically worthwhile effect to be demonstrated.
Although traditionally sample size calculations are often based on the smallest clinically worthwhile effect size, the same mathematical approach can be applied using the meta-analysis point estimate instead since this can be considered the expected treatment effect.
Metal Gear Solid V: The Phantom Pain, incomplete as it is, also forms a worthwhile take on the effects of The Cold War era, letting the player take part in both the Soviet-Afghan War and the Angolan Civil War as legendary hero Big Boss.

Not everything that is worthwhile has an immediate positive effect on financial bottom lines, or can be put neatly in a box.
It is worthwhile noticing that the sample size also has a direct effect on this behavior and may increase spurious detection of linkage disequilibrium.
