Quantitative relations between baseline iron status , study duration , and iron dose on changes in iron-status biomarkers , which were generated from the meta-analyses , can be used to predict effects of trials of iron supplementation and fortification and to design iron-intervention programs
BACKGROUND The response of status biomarkers to an increase in iron supply depends on several physiologic and environmental factors , which make it difficult to predict the outcome of an intervention .
OBJECTIVE We assessed effects of baseline iron status , sex , menopausal status , duration of intervention , iron form , and daily dose on the change in iron status in response to iron supplementation .
Effect of oral iron therapy on the symptoms of anaemia.
In a study published elsewhere ( Wood and Elwood , 1966 ) the associations between the severity of various symptoms and haemoglobin levels in subjects who took part in a community survey is described . The present paper describes a double-blind r and omized clinical trial of the effects on these symptoms of  oral iron therapy  in a sample of the women seen during the community survey . In addition some limited data relating to a separate trial conducted in severely anaemic women identified in a hospital out-patient clinic are presented
