It is therefore recommended that measures of iron and vitamin A status are adjusted for inflammation.51,52 One of the studies showed that 38% of its study population had subclinical inflammation (measured with CRP and AGP), which turned out not to be associated with anemia.13 None of the other 10 studies included have made adjustments for inflammation, and therefore reported ID may be underestimated, and vitamin A deficiency may be overestimated. The gene discussed is ATP5MK; the disease is anemia.
