The Claim

Cardiovascular-kidney-metabolic syndrome is associated with a 62% higher odds of dual sensory impairment when comparing Stage 4 to Stage 1 rather than Stage 0, and this association remains robust across alternative reference groups and sensitivity analyses.

In plain English

People with advanced cardiovascular-kidney-metabolic syndrome have a higher likelihood of experiencing both hearing and vision loss compared to those with milder forms of the condition, even when accounting for different comparison groups.

See the scientific wording

The association between cardiovascular-kidney-metabolic syndrome and sensory impairments remains robust even when using alternative reference groups and sensitivity analyses, including a 62% higher odds of dual sensory impairment when comparing Stage 4 to Stage 1 rather than Stage 0, indicating that the relationship is not driven by an unusually healthy reference group.

Why this might work

Long-term high blood sugar and high blood pressure damage tiny blood vessels in the ears and eyes, reducing blood flow and causing inflammation. This kills cells needed for hearing and sight. At the same time, the same damage spreads to brain areas that combine hearing and vision signals, making it harder for the brain to process both senses together.

    Even when comparing people with the worst heart, kidney, and metabolism problems to those with just early signs (not the healthiest people), the risk of losing both hearing and vision is still much higher — proving the link is real and not just because they compared to super healthy people.
