Provide a general description of the methods as reported by the authors. Information should be extracted based on relevance to the SR (i.e., caffeine related methods) 592 healthy Moroccan men (age 20-79); recruitment via hospital staff, university students and lay people contacted by word of mouth and through advertisements (not a true probability sample of population). Each subject completed a standardized questionnaire on life style, smoking habits, and level of physical activity in leisure time, along with calcium consumption and the use of vitamins and medications. The men were asked whether they usually drank milk, coffee, soft drinks or alcohol; if the answer was positive, they were asked to quantify their average current consumption. Coffee was categorized as high, moderate and low coffee consumption (more than 3, 1-2 and less than 1 cups/day, respectively). Height and weight were measured, and BMI calculated. The BMD of the lumbar spine and proximal right femur measured in volunteers with no previous history of bone disease using a Lunar Prodigy Vision DXA system. Patient BMD was measured at the lumbar spine (anteroposterior projection at L1-L4 and L2-L4, but only L2-L4 results were presented to be compared with the published studies). The World Health Organization (WHO) classification system was applied, defining osteoporosis as T-score ≤-2.5 and osteopenia as -2.5 < Tscore < -1. Comparison between patients according to the WHO classification system was done using analysis of variance (ANOVA) for quantitative variables and chisquare test for qualitative variables. Stepwise multiple regression analysis was then used to study the determinants of BMD. The level for significance was taken as p ≤ 0.05

What were the listed confounders or modifying factors as stated by the authors? (e.g. multi-variable components of models.  Copy from methods) Multiple determinants of BMD (not clearly listed, but assumed to include lifestyle, smoking habits, level of physical activity in leisure time, calcium consumption, use of vitamins and medications, and consumption of various beverages). Data for all variables not clearly shown.
