to evaluate the quality of information on the Internet concerning varicose veins.
review of retrieved pamphlets and their scoring for educational value.
a sample of 41 documents were retrieved from the Internet using four "search engines".
characteristics, including country of origin, authorship, length, and presence of references were recorded. Based on factors such as disease summary, treatment options and complications a weighted score was created by two independent observers.
eleven documents were published by an academic institution or professional organisation. Twenty-seven documents originated from private practice groups, the source of three was unidentifiable. The median weighted score was 21.5 (interquartile range: 7.5-48.5). Scores originating from non-profit making organisations were significantly higher than those from private practice groups (44.5 vs 13, p=0.04). The length of the document showed a significant positive correlation with its educational quality as measured by the information score (r=0.82, p<0.001).
there is a plethora of data concerning varicose veins on the Internet. Some documents offer comprehensive information but many are confusing or misleading. Longer pamphlets and information presented by non-profit making organisations are more reliable than short documents and information offered by private medical groups.
评估互联网上有关静脉曲张信息的质量。
对检索到的宣传册进行审查并对其教育价值进行评分。
使用四个“搜索引擎”从互联网上检索了41份文档样本。
记录文档的特征，包括来源国、作者、篇幅以及参考文献情况。由两名独立观察员根据疾病概述、治疗选择和并发症等因素创建加权分数。
11份文档由学术机构或专业组织发表。27份文档来自私人执业团体，3份来源不明。加权分数中位数为21.5（四分位间距：7.5 - 48.5）。来自非营利组织的分数显著高于私人执业团体（44.5对13，p = 0.04）。文档篇幅与信息分数衡量的教育质量呈显著正相关（r = 0.82，p < 0.001）。
互联网上有大量关于静脉曲张的数据。一些文档提供了全面的信息，但许多文档令人困惑或具有误导性。篇幅较长的宣传册以及非营利组织提供的信息比私人医疗团体提供的短文档和信息更可靠。
