GHRP-2 in sarcopenia and lean-mass preservation during weight reduction — evidence extract
The Institute's graded assessment of GHRP-2 for sarcopenia and lean-mass preservation during weight reduction, with the contributing trials and the domain-by-domain certainty reasoning.
§1Evidence extract: Sarcopenia and lean-mass preservation during weight reduction
§1.1Question and anchor outcome
- Population
- Loss of skeletal muscle mass and function, considered here principally as a consequence of rapid weight reduction under incretin therapy.
- Intervention
- GHRP-2, intravenous for the approved diagnostic use; subcutaneous in research contexts
- Comparator
- As used in each contributing trial; reported per trial rather than pooled across comparator types
- Anchor outcome
- Change in appendicular lean mass by DXA
Additional outcomes the Institute extracts for this indication: Change in fat-free mass by MRI; Grip strength; Physical performance battery.
§1.2Contributing trials
No trial has been identified for GHRP-2 in sarcopenia and lean-mass preservation during weight reduction. The rating below reflects that absence.
§1.3Certainty assessment
Table 2. Reasoning recorded against each certainty domain.
| Domain | Rating | Reasoning |
|---|---|---|
| Risk of bias | Serious | The primary endpoint is patient-reported in a setting where blinding cannot be maintained. |
| Inconsistency | Serious | Direction is consistent; magnitude varies with the intensity of the background intervention. |
| Indirectness | Serious | The enrolled population differs materially from the population of the assessment question. |
| Imprecision | No concern | No serious concern identified in this domain. |
| Publication bias | No concern | No serious concern identified in this domain. |
| Overall rating: Very low certainty. The Institute has very little confidence in the effect estimate. The true effect is likely to be substantially different from the estimate. In this series a very low rating most often reflects an absence of controlled human evidence rather than conflicting evidence. | ||
