After damaging the eye tissue with enzymes, the special peptide reduced broken collagen levels compared to a saline solution, as seen with a fluorescent marker.
Scientific Claim
In rat optic nerve head tissues, collagen mimetic peptide-3 (CMP-3) treatment after MMP-1 damage is associated with reduced collagen fragmentation compared to vehicle control, as measured by R-CHP peptide binding fluorescence.
Original Statement
“After collagen digestion with MMP-1 and subsequent CMP-3 addition, the level of fragmented collagen was reduced and comparable to the baseline (Figure 3B(1c)).”
Evidence Quality Assessment

appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The study design is treated as non-causal evidence per GRADE analysis, so using 'associated with' is appropriate. The description of reduced fluorescence is accurately reported from the data.
