Figure 1: Box plots of iron status indices in 12-month olds, from previous (1995–1997) and present (2005–2007) studies. The box plots show the median, quartiles, maximum, and minimum values. Independent 𝑡 -test was used for hemoglobin ( 𝑃 = . 0 0 1 ), and MCV ( 𝑃 = . 1 1 3 ), data were normally distributed and Mann-Whitney test for serum ferritin ( 𝑃 = . 0 0 1 ) data were not normally distributed.
