From: The share of ultra-processed foods and the overall nutritional quality of diets in the US: evidence from a nationally representative cross-sectional study

Fig. 1

“Nutrient balanced pattern” factor score regressed on the dietary share of ultra-processed foods evaluated by restricted cubic splines, US population aged 1+ years (NHANES 2009–2010) (N = 9,317). Legend: The values shown on the x-axis correspond to the 5th, 27.5th, 50th, 72.5th, and 95th percentiles for percentage of total energy from ultra-processed foods (knots). Coefficient for linear term = -0.03, 95% CI: -0.04 to -0.02 (beta = -0.35). There was little evidence of nonlinearity in the restricted cubic spline model (Wald test for linear term p < 0.001; Wald test for all non-linear terms p = 0.16)
