§1Evidence extract: Growth hormone deficiency and growth-hormone secretagogue pharmacology

§1.1Question and anchor outcome

Population
Insufficient endogenous growth-hormone secretion, or the pharmacological stimulation of the growth-hormone axis, assessed here principally through provocative testing and IGF-1 response.
Intervention
CJC-1295, subcutaneous
Comparator
As used in each contributing trial; reported per trial rather than pooled across comparator types
Anchor outcome
Peak stimulated growth hormone

Additional outcomes the Institute extracts for this indication: Change in IGF-1 and IGFBP-3; Body composition by DXA; Glucose tolerance.

Figure 2. Domain-by-domain certainty assessment for CJC-1295 in growth hormone deficiency and growth-hormone secretagogue pharmacology. The starting rating for a body of randomised evidence is high; each serious concern reduces it by one level and each very serious concern by two.

Table 2. Reasoning recorded against each certainty domain.

DomainRatingReasoning
Risk of biasSeriousThe primary endpoint is patient-reported in a setting where blinding cannot be maintained.
InconsistencySeriousToo few contributing studies to assess consistency formally.
IndirectnessNo concernNo serious concern identified in this domain.
ImprecisionNo concernNo serious concern identified in this domain.
Publication biasNo concernNo serious concern identified in this domain.
Overall rating: Low certainty. Confidence in the effect estimate is limited. The true effect may be substantially different from the estimate.
