> ... but it's entirely possible to get significant results from small sample sizes. It is also possible to simply guess some effect. You don't need study for stating a result. A purpose of study is to prove something. A study that can not be told to be proven and is not replicable is not worth anything, as further scientific knowledge cannot be built on top of it. If a study do not prove or at least strengthen confidence in a theory, what is it worth? Not even meta-analysis will consider studies like these to prove some entirely different theory because it is just that unreliable. Now I'm not saying this particular study is entirely like that, but the flaws everyone mentioned are concerning.
