Unusual for carrying imaging and biomarker endpoints — WOMAC, quality of life, MOAKS parameters and CTX-II — rather than symptom scores alone. The headline is a potency claim: 2.5 g of the branded peptide improved outcomes significantly and was reported as equivalent to 10.0 g of a conventional peptide.

Population

Adults with knee joint osteoarthritis, five arms

Intervention

2.5, 5.0 or 10.0 g of a branded 'Type J' bovine collagen peptide, or 10.0 g of a conventional peptide

Comparator

Placebo, 5.0 g in the design table and 10.0 g in the abstract

Limitations

Twenty per arm across five arms. Multiple authors are employed by Nitta Gelatin India Limited and affiliated companies, and 'Type J', the branded peptide reported as matching the conventional peptide at a quarter of its dose, is their commercial product. No confidence intervals in the abstract, and 90 days is short for the structural endpoints included. By design, 115 were enrolled and the first 100 to complete were analysed, so the analysis is per protocol.
