Chiropractic and bedwetting -- an example of bad scientific claims

The claim, by Maxmized Living, citing a specific publication on bedwetting:

ML has a practice of citing scientifically questionable studies by this "Journal of Manipulative and Physiological Therapeutics," which looks to be nothing more than a conduit for bad and deceptive science for chiropractic. The strategy appears to be that if you have no science on your side, make up some fake science and use that.
