longitudinal design is good but where are the spaghetti plots.
- n8henrie 3y agoLongitudinal design would usually refer to an observational study, but lest other readers be confused by your comment, this is -- from the title -- a "a randomised, double-blind, placebo-controlled study." In my opinion, compared to numerous studies in the same category, the placebo seems very reasonable, and the dose-dependent effect size seems highly suggestive of a real effect. I hope additional / larger studies confirm the effect, and if so that a metabolic ward study can help us determine where the effect is taking place! (Food diaries are better than nothing, but notoriously inaccurate.)
- SubiculumCode 3y agoIts longitudinal in the sense that they are measuring change in outcome variables over time, even if in this case its not over the period of years. In this case it is a longitudinal randomized experiment.
