T98 0-31 Sentence denotes Limitations of current research
T99 32-172 Sentence denotes Lack of high-quality evidence (especially randomized controlled trails [RCTs]) is the most important limitation of the current CoV research.
T100 173-462 Sentence denotes As most of the CoV strains are genetically different and the outbreaks occur extremely randomly, conducting an RCT is extremely difficult, and we have to rely on observational studies (most of which do not have proper control group), which hamper the estimation of proper treatment effect.
