Fig. 6: Comparison of model coefficients for for M₁ models fit to the full cohort, and for M_{1,race−ethn.} models fit independently to each race/ethnicity group.

a–e (top row) correspond to models fit using mean daytime SpO₂. f–j (bottom row) correspond to models fit using mean nocturnal SpO₂. Regression coefficients consist of: a, f constant term, b, g age, c, h body mass index, d, i home altitude, e, j assigned sex. Error bars represent 99.5% confidence intervals for the fitted coefficients. Plotted coefficients and confidence intervals are identical to the values listed in Supplementary Table 6.
