BPC-157 in knee osteoarthritis with obesity — evidence extract
The Institute's graded assessment of BPC-157 for knee osteoarthritis with obesity, with the contributing trials and the domain-by-domain certainty reasoning.
§1Evidence extract: Knee osteoarthritis with obesity
§1.1Question and anchor outcome
- Population
- Degenerative joint disease of the knee with radiographic or symptomatic confirmation, occurring with obesity as a mechanical and inflammatory contributor.
- Intervention
- BPC-157, subcutaneous, intraperitoneal or oral in preclinical studies; subcutaneous or oral in research contexts
- Comparator
- As used in each contributing trial; reported per trial rather than pooled across comparator types
- Anchor outcome
- WOMAC pain subscale
Additional outcomes the Institute extracts for this indication: Physical function score; Analgesic use; Progression to arthroplasty.
§1.2Contributing trials
No trial has been identified for BPC-157 in knee osteoarthritis with obesity. The rating below reflects that absence.
§1.3Certainty assessment
Table 2. Reasoning recorded against each certainty domain.
| Domain | Rating | Reasoning |
|---|---|---|
| Risk of bias | No concern | No serious concern identified in this domain. |
| Inconsistency | Serious | Too few contributing studies to assess consistency formally. |
| 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 | Serious | Registered trials without posted results were identified for this question. |
| 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. | ||
