Figure 3. Illustrative. Assessed outcomes plotted on a common standardised axis so that direction and relative magnitude can be compared at a glance. The estimates are not on a common natural scale and the intervals are the Institute's standardised representation of the reported precision, not the published confidence intervals. Published intervals appear in the per-indication extracts and in the text below.

§3.1Biological ageing and healthspan endpoints

Anchor outcome. Epigenetic age acceleration.

Effect as recorded. No assessable evidence identified; —.[1,2]

Certainty. Very low certainty

Contributing trials. None identified. The rating reflects an absence of controlled evidence rather than conflicting evidence.

§3.2Immune modulation and adjunctive immunotherapy

Anchor outcome. CD4 and CD8 counts.

Effect as recorded. Russian clinical reports describe immunological and clinical effects across a wide range of conditions; not extractable to the Institute's standard.[2,3]

Certainty. Very low certainty For a substance of undefined composition, the Institute cannot in principle assign a certainty rating above very low, because the intervention itself is not specified.

Contributing trials. THYMALIN-RU-1. Full structured abstracts are published for each.
