In our experience, complaints of ankle swelling are more common in summer, typically from patients with no obvious cardiovascular disease. Surprisingly, this observation has never been reported. To objectively establish this phenomenon, we sought evidence of seasonality in the public's Internet searches for ankle swelling. Our data, obtained from Google Trends, consisted of all related Google searches in the United States from January 4, 2004, to January 26, 2016. Consistent with our expectations and confirmed by similar data for Australia, Internet searches for information on ankle swelling are highly seasonal (highest in midsummer), with seasonality explaining 86% of search volume variability.
根据我们的经验，脚踝肿胀的投诉在夏季更为常见，通常来自没有明显心血管疾病的患者。令人惊讶的是，这一观察结果从未被报道过。为了客观地证实这一现象，我们寻找公众在互联网上搜索脚踝肿胀的季节性证据。我们从谷歌趋势获得的数据包括2004年1月4日至2016年1月26日在美国的所有相关谷歌搜索。与我们的预期一致，并得到澳大利亚类似数据的证实，关于脚踝肿胀信息的互联网搜索具有高度季节性（仲夏时最高），季节性解释了86%的搜索量变化。
