Table 3 The difference across the three dairy groups using ANCOVA

From: The effects of changing dairy intake on trans and saturated fatty acid levels- results from a randomized controlled study

Trans fatty acid

Reduced dairy intake

Same dairy intake

Increased dairy intake

Across all three groups P

  1. ANCOVA was used unless assumptions were not met. ANOVA was used for all others (Table 4) Fatty acids are standardized to d4- alanine and presented as median (interquartile range).
