Ferritin formation per half a gram of freeze-dried green leafy vegetables. Vertical lines are means with 95% confidence intervals of ng ferritin/mg protein from the various greens (n = 12 for corchorus; n = 18 for OFSP1, PFSP, baobab, kenaf and moringa; and n = 21 for OFSP2, OFSP3, WFSP and cocoyam) normalised to the blank digest ferritin level; horizontal line indicates the overall mean of ng ferritin/mg protein; means with 95% confidence intervals with a different letter (a,b) are significantly different (p < 0.0001).
