Dear Editor, We thank Dr. Jian Xie for the valuable inputs on our paper titled 'Chronic mechanical irritation and oral squamous cell carcinoma: A systematic review and meta-analysis [1].' The first concern of Dr. Xie was that we had included two studies that were based on the same population. We re-examined these papers, one was published in 2010 [2] and the other in 2017 [3] by the same group of authors. Given the significant time difference between the two papers, we did not want to presume they were from the same sample population. There is no clear evidence that they are from the same sample population. Read more in PDF.

回复关于“慢性机械刺激和口腔鳞状细胞癌：系统评价和荟萃分析”的来信。

尊敬的编辑，感谢Jian Xie 博士对我们题为“慢性机械刺激和口腔鳞状细胞癌：系统评价和荟萃分析[1]”的论文提供的宝贵意见。谢博士首先担心的是，我们纳入了两项基于相同人群的研究。我们重新审查了这些论文，一篇发表于 2010 年 [2]，另一篇发表于 2017 年 [3]，由同一组作者发表。鉴于两篇论文之间的显着时间差异，我们不想假设它们来自相同的样本群体。没有明确的证据表明它们来自同一样本人群。在 PDF 中阅读更多内容。
