Jeff Langmaid analyzed X-rays and found a strong correlation between age and degenerative changes. Patients with no degeneration had a median age of 25, while those with severe changes averaged 63. The relationship held across all severity levels.
The key finding was age and degeneration were very strongly related, and that was the clearest finding. The correlation was 0.783, and that's a super strong relationship, 95% confidence interval. So in plain English, as age went up, degeneration on the X-rays went up substantially. And the raw numbers made this, you know, even easier to appreciate. The median age of patients with no degenerative changes, 25. The median age among patients with severe degenerative changes, So gigantic separation right there, and it showed us that as you move from none to mild to moderate to severe, the age distribution shifted upwards appropriately.
