Table 1 Prevalence (%) of any anemia (using two defintiions: defined as a hemoglobin concentration < 140 g/ in men and < 130 g/L in women, or defined as a hemoglobin concentration < 130 g/ in men and < 120 g/L in women), mild anemia (using two defintiions: defined as a hemoglobin concentration < 140 g/L and > 110 g/L in men; < 130 g/L and > 110 g/L in women, or defined as a hemoglobin concentration < 130 g/L and > 110 g/L in men; < 120 g/L and > 110 g/L in women) and moderate anemia (hemoglobin concentration < 110 g/L and > 80 g/L) in the Ural Eye and Medical Study, stratified by sex and age
