A specific red light treatment made cartilage cells in a dish produce more of a key structural protein that helps keep joints healthy

Evidence Quality Assessment

Claim Status

appropriately stated

Study Design Support

Design supports claim

Appropriate Language Strength

definitive

Can make definitive causal claims

Assessment Explanation

The study directly measured aggrecan expression with no statistical significance for this specific parameter, so 'did not alter' is appropriate.

More Accurate Statement

“Near-infrared light at 850 nm with 4 mW/cm² power density, pulsed mode, applied every other day for 120 seconds, did not significantly alter aggrecan expression in cultured human chondrocytes from a 46-year-old female donor”
