The aim of the study was to elucidate possible sex differences in knowledge, competence and attitudes behind decision-making on cobalamin-associated problems (vitamin B(12)). The study was conducted by postal questionnaires to Swedish physicians in 1996-98. The participants were recruited by random sampling of general practitioners (1996, 1998), and a total sampling of geriatricians (1998). The overall response rate was 71%. The study group comprised 480 female physicians and 526 male physicians. The responses to 24 statements in the questionnaire were measured by means of visual analogue scales. Group differences were evaluated by medians and shapes of distributions. The female doctors appeared to value patient-related symptoms and signs more than male doctors. Conversely, male doctors relied on laboratory tests more than female doctors. As reflected by questionnaire answers, female doctors appeared to be more informed than male doctors on cobalamin-associated clinical problems. Group differences between the sexes were marginal from a numerical point of view. It is suggested that the statistical differences observed should be regarded as negligible until confirmed by further studies.
该研究的目的是阐明在钴胺素相关问题（维生素B12）决策背后的知识、能力和态度方面可能存在的性别差异。该研究于1996 - 1998年通过向瑞典医生邮寄问卷的方式进行。参与者通过对全科医生的随机抽样（1996年、1998年）以及对老年病医生的全样本抽样（1998年）招募。总体回复率为71%。研究组包括480名女医生和526名男医生。问卷中24项陈述的回答通过视觉模拟量表进行测量。通过中位数和分布形状评估组间差异。女医生似乎比男医生更重视与患者相关的症状和体征。相反，男医生比女医生更依赖实验室检查。从问卷答案可以看出，女医生在钴胺素相关临床问题上似乎比男医生了解得更多。从数值角度来看，两性之间的组间差异很小。建议在进一步研究证实之前，所观察到的统计差异应被视为可忽略不计。
