"90% of our patients see improvement." This claim — or something very like it — appears on the marketing materials of nearly every stem cell clinic worldwide. It sounds convincing. But what does "improvement" mean? How was it measured? Over what timeframe? And who was excluded from the count? These questions are the difference between a meaningful outcome statistic and a marketing fabrication.
Clinic-reported success rates are marketing claims, not clinical evidence. They are typically unverified, use undefined outcome measures, exclude non-responders, and lack comparison to placebo or standard-of-care treatment. Published, peer-reviewed studies are the only reliable source of outcome data.
| Claim Element | What to Ask | Why It Matters |
|---|---|---|
| '90% success rate' | 'How do you define success?' | 'Any improvement' is very different from '50%+ pain reduction on VAS' |
| 'Most patients see improvement' | 'What percentage of ALL treated patients — not just responders — improved?' | Excluding non-responders inflates the number dramatically |
| 'Long-lasting results' | 'At what timepoint was this measured?' | 4-week results vs 12-month results are very different claims |
| 'Published outcomes' | 'Can you cite the specific study? Is it peer-reviewed?' | Clinic-published white papers are not peer-reviewed research |
| 'Patient testimonials' | 'Are these verified? Do you track all patients or only satisfied ones?' | Selection bias: only happy patients provide testimonials |
| Success rate in general | 'Do you participate in a patient outcome registry?' | Registries track ALL patients systematically; marketing does not |
What Good Outcome Reporting Looks Like
A clinic committed to honest outcome reporting will use validated outcome measures (VAS pain scale, WOMAC for joints, DAS28 for RA, EDSS for MS), report results as intention-to-treat (including all patients, not just completers), specify the timepoint (3 months, 6 months, 12 months), publish or submit to peer review, participate in a patient outcome registry, and be transparent about non-responders and adverse events.
