The World Health Organization (WHO) announced in a press conference on January 29, 2020 that the death rate of COVID-19 was 2% on the case fatality rate (CFR). It was underestimated assuming no lag days from symptom onset to deaths while many CFR formulas have been proposed, the estimation on Bays theorem is worthy of interpretation. Hence, it is hypothesized that the over-loaded burdens of treating patients and capacities to contain the outbreak (LSBHRS) may increase the CFR. Methods We downloaded COVID-19 outbreak numbers from January 21 to February 14, 2020, in countries/regions on a daily basis from Github that contains information on confirmed cases in >30 Chinese locations and other countries/regions. The pros and cons were compared among the 5 formula of CFR, including [A] deaths/confirmed; [B] deaths/(deaths + recovered); [C] deaths/(cases x dafinal CFR. An app developed for displaying the provisional CFR with the 2 CFR trends can improve the underestimated CFR reported by WHO and media.Background Functional dyspepsia (FD) is a chronic gastrointestinal disorder diagnosed with dyspeptic symptoms, such as recurrent or persistent postprandial fullness, epigastric pain, burning, and early satiety without any evidence of structural abnormality. In traditional Korean medicine, herbal remedies are one of the preferred treatments for gastrointestinal symptoms. Among them, Naesohwajung-tang (NHT) has been frequently prescribed to improve dyspeptic symptoms for a long time. However, the safety and efficacy of NHT still remain unclear. Therefore, this study aims to evaluate the safety and efficacy of NHT in patients with FD using a randomized controlled trial. Methods This is a protocol for a multi-center, randomized, double-blind, placebo-controlled trial. Tot
