Randomized Controlled Trial Comparative Study
Randomised controlled trial of Alexander technique lessons, exercise, and massage (ATEAM) for chronic and recurrent back pain: economic evaluation.
An economic evaluation of therapeutic massage, exercise, and lessons in the Alexander technique for treating persistent back pain. ⋯ An exercise prescription and six lessons in Alexander technique alone were both more than 85% likely to be cost effective at values above pound20 000 per QALY, but the Alexander technique performed better than exercise on the full range of outcomes. A combination of six lessons in Alexander technique lessons followed by exercise was the most effective and cost effective option.

Comparative Study
Discrepancies in sample size calculations and data analyses reported in randomised trials: comparison of publications with protocols.
To evaluate how often sample size calculations and methods of statistical analysis are pre-specified or changed in randomised trials. ⋯ When reported in publications, sample size calculations and statistical methods were often explicitly discrepant with the protocol or not pre-specified. Such amendments were rarely acknowledged in the trial publication. The reliability of trial reports cannot be assessed without having access to the full protocols.
