With the ongoing pandemic of coronavirus disease 2019 (COVID-19), there is an argument on whether we should increase the number of testing for the coronavirus (SARS-CoV-2) to mitigate the epidemic in a given country. Therefore, we investigated the correlation between testing number and mortality to evaluate the hypothesis.
Data on an open-access database of COVID-19 was retrieved. Member countries of the Organization for Economic Co-operation and Development (OECD), BRICs nations (Brazil, Russia, India, and China), and Taiwan were included in the analysis, but 2 countries were removed as outliers.
There was a weak, positive correlation between mortality and testing (r = 0.34, 0.03). On regression analysis, there was a positive slope but the coefficient was very small (0.00064).
We found a very small positive correlation between testing number and mortality for COVID-19.
随着2019冠状病毒病（COVID-19）大流行的持续，对于在特定国家是否应增加冠状病毒（严重急性呼吸综合征冠状病毒2，SARS-CoV-2）检测数量以缓解疫情存在争议。因此，我们研究了检测数量与死亡率之间的相关性以评估该假设。
检索了COVID-19开放获取数据库中的数据。经济合作与发展组织（经合组织）成员国、金砖国家（巴西、俄罗斯、印度和中国）以及台湾地区被纳入分析，但剔除了2个作为异常值的国家。
死亡率与检测之间存在微弱的正相关（r = 0.34，P = 0.03）。回归分析显示存在正斜率，但系数非常小（0.00064）。
我们发现COVID-19的检测数量与死亡率之间存在非常小的正相关。
