We would like to correct the authors’ interpretation of ‘Preoperative intravenous iron to treat anaemia before major abdominal surgery (PREVENTT): a randomised, double-blind, controlled trial’ [2] in their introduction. As baseline iron studies were not routinely assessed in the UK [3] iron studies were performed at randomisation. Overall, 82% of patients had iron deficiency anaemia and these results were reported as per the statistical analysis plan in the predefined subgroup analysis. Analysis by baseline iron deficiency showed no meaningful difference in terms of the patient outcomes of the trial.

致编辑的信，以回应“术前静脉铁剂对接受结直肠癌手术的贫血患者的动态影响”

我们想更正作者在引言中对“腹部大手术前静脉铁剂治疗贫血 (PREVENTT)：一项随机、双盲、对照试验”[2] 的解释。由于在英国没有常规评估基线铁研究 [3]，铁研究是随机进行的。总体而言，82% 的患者患有缺铁性贫血，这些结果是根据预定义的亚组分析中的统计分析计划报告的。基线缺铁分析显示，在试验的患者结果方面没有显着差异。
