Données incorrectes: Dans l'article original intitulé "Vitamin E and Respiratory Tract Infections in Elderly Nursing Home Residents: A Randomized Controlled Trial" publié dans le numéro du 18 août 2004 du JAMA (2004;292:828-836), des données incorrectes apparaissent sur l'état nutritionnel dans le tableau 2. Le tableau corrigé est présenté ici. Par ailleurs, le texte corresondant à ce tableau page 832 devait être lu de la façon suivante: "Except for vitamin E, the level of micronutrients did not change significantly during the study period in either group. Plasma vitamin E levels increased significantly in the vitamin E group, which doubled after 3 months of supplementation with no further change (mean [SD], 1141 [391] vs 2119 [689] µg/dL before and after supplementation, respectively, P<.001). No significant change in serum vitamin E levels was observed in the placebo group (1148 [429] vs 1209 [408] µg/dL before and after supplementation, respectively). The fraction of participantswith low vitamin D and B₆ levels decreased in both groups (Table 2), with no significant difference between treatments in change over time. Significantly fewer participants had low hemoglobin levels in the vitamin E group after supplementation (Table 2). The fraction of participants with low hemoglobin levels in each group did not change significantly over time. Low serum zinc levels were equally prevalent in both groups (Table 2)."
