Long description

A line graph illustrates a relationship between the decreased risk of colorectal cancer and increased consumption of dietary fibre. The horizontal axis is labelled ‘dietary fibre’ (in grams per day) and ranges from 0 to 40 in increments of 10 units. A rightward arrow labelled ‘increased fibre intake’ is drawn along the horizontal axis. The vertical axis is labelled ‘estimated relative risk’ and ranges from 0.00 to 1.00 in increments of 0.20 units. A kink is present between 0.00 and 0.60. A downward arrow labelled ‘decreased risk’ is drawn along the vertical axis. The line graph shows a line with a negative slope trending downward from upper left to lower right. A line starts from 3.85 grams per day of dietary fibre with an estimated relative risk of 1.00. The line drops gradually and passes through the following points: fibre intake of 10 grams per day decreases risk to 0.92; fibre intake of 20 grams per day decreases risk to 0.83; fibre intake of 30 grams per day decreases risk to 0.78; fibre intake of 40 grams per day decreases risk to 0.66. All values are approximated.
