Relationship of Sn in urine with dietary Sn intake after logarithmic conversion. Each dot indicates one case and the solid line in the middle is a calculated regression line. Two broken curves on both sides of the line indicate the 95 % range for the regression line. Note that the range of distribution is wide and that the regression line is almost in parallel to a horizontal line
