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.

§3.1Growth hormone deficiency and growth-hormone secretagogue pharmacology

Anchor outcome. Peak stimulated growth hormone.

Effect as recorded. Marked acute growth-hormone release; the response attenuates substantially over 8 to 16 weeks of continuous administration; pharmacodynamic.[1,2]

Certainty. Low certainty Tachyphylaxis is the defining clinical limitation and is documented in the historical literature.

Contributing trials. HEX-PH1-GH · HEX-PH2-ELDERLY. Full structured abstracts are published for each.

§3.2Atherosclerotic cardiovascular disease and cardiovascular risk reduction

Anchor outcome. Three-point major adverse cardiovascular events (cardiovascular death, non-fatal myocardial infarction, non-fatal stroke).

Effect as recorded. No randomised human evidence identified; —.[2,3]

Certainty. Very low certainty Cardioprotective claims derive entirely from rodent models.

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