For quantitative detection products, appropriate statistical analysis methods such as regression analysis should be selected according to the detection performance of the products for clinical trial results. Within a reasonable confidence interval, investigate whether there was a significant correlation and whether there is a significant statistical difference in the results of quantitative values.
If possible, the recommendation should be taken into account that the possible differences in the performance of reagents in different sample concentration intervals, the overall concentration range is subject to interval stratified statistics, and the results in different concentration intervals were analyzed for correlation to better verify the correlation between the two reagents.
