When a clinic is ranked
A rank is a strong signal, so we only assign one when the evidence supports it. Clinics without enough independent, verifiable evidence are shown as “Listed, not ranked” — that is a statement about evidence coverage, not a verdict on the clinic.
Absence of evidence is not evidence of safety
A clinic with few public records is not automatically low-risk — it may simply be new, small, or lightly reviewed. Rather than invent a score, we hold it out of the ranking and label it “Listed, not ranked — insufficient evidence coverage.” No rank number is shown until the threshold below is met.
Five things a clinic must have to be ranked
How sure we are — separate from the score
Every assessment carries a Confidence Grade (out of 100) built from source diversity, time coverage, usable volume, evidence completeness and reviewer quality. It is kept separate from the clinic’s score, so you can see how strong the evidence is, not just what it says.
Reading the register
A clinic marked “Listed, not ranked” has a verified public presence but not yet enough independent evidence for a confident assessment. As more verifiable records accumulate, it can cross the threshold and enter the ranking. The full weighting is set out in the ranking methodology.
