Prevention course participants seem to have characteristics that differ from the average population (higher health orientation level, preference for prevention over medical treatment services, etc.) and cannot be captured by secondary data; therefore, matchings based on secondary data alone cause selection bias. Including both primary and secondary data reduces the risk of selection bias in matching procedures for prevention studies. The E-value can be used to evaluate the robustness of results with regard to selection bias.

The purpose was to investigate the effects of yoga and clinical Pilates training on walking, respiratory muscle strength, cognition, and quality of life and compare the effects of two popular exercise methods in persons with multiple sclerosis (pwMS). Twenty-eight pwMS (Pilates group=16, yoga group=12) received the program once a week for eight weeks in addition to home exercises. At baseline and the end of the training, participants underwent assessments. The outcome measures were walking speed, mobility, balance confidence, respiratory muscle strength, cognition, and quality of life. Following the program, there was no significant difference in mobility (p=0.482), perceived walking quality (p=0.325), respiratory muscle strength (maximum inspiratory pressure p=0.263, maximum expiratory pressure p=0.866), and cognition (Symbol Digit Modalities Test p=0.324, California Verbal Learning Test-II p=0.514, Brief Visuospatial Memory Test-Revised p=0.279) between the two groups. Improvements were higher in balance confidence (p=0.006), walking speed (p=0.004), and qualit
