What methodological flaws often invalidate the results reported by private stem cell clinics?
Answer
Small sample sizes, lack of standardized protocols, and absence of control groups
Clinical evaluations performed by many private clinics suffer from systemic weaknesses that make it impossible to determine if the reported improvements are genuine. Without control groups, researchers cannot discern if changes are due to the therapy, a placebo effect, or natural developmental progress. Furthermore, the lack of standardized protocols regarding dosage, frequency, and cell types means that results are inconsistent and difficult to replicate or validate through scientific inquiry.
