Characteristics of the subjects within two subgroups defined by milk intake at baseline
| Mean (or %) | Men with median* total milk intakes or less | Men with total milk intakes above the median* | Probability |
|---|---|---|---|
| The data shown are percentages, or means and SDs as appropriate. Missing values as follows: smoking, four men; occupation (social class) 14 men; serum total cholesterol 38 men; triglycerides 47 men; homocysteine 156 men. These were equally divided between the two subgroups of the men and for no other variable were there missing values. *The median intake of all milk and from all sources was 195 cc per day. †Based on the man’s occupation at baseline, using the registrar general UK’s classification. ‡Median intake and interquartile range. §Estimates adjusted for energy intake. ¶Estimates derived from fasting blood samples. | |||
