Method We used the Excel formula x=EXP(‐tn*0.693/t1/2) to calculate proportion of residual patients remaining progression‐free at different times, where tn is the interval in weeks between scans (eg, 6weeks), * indicates multiplication, 0.693 is the natural logarithm of 2, and t1/2 is...
The authors first extracted the relevant data from the selected studies, entered the data into Microsoft Excel 2016, and used R statistical software to assess the outcomes. A table and a forest plot were used to represent and report the results. By applying the binomial distribution formula, the...
Figure4, delineates the box plot for each mortality-related indicator and contains a plot for both complete and imputed data. The visual inspection of the box plots suggests that till a missing proportion of 50%, the imputed data is slightly changing from the complete data. Whereas, the imput...
The parameter p serves to regulate the proportion of computational resources that are allocated to the convergence stage, in addition to the other stages. A smaller value of p indicates that the convergence stage has a diminished role in the overall evolutionary process. Conversely, the convergence...
It is possible to express the Incidence of Pneumonia using three different measures: the “Incidence Rate” that is the cases/person-year ratio, in our study 1220/96,950 = 0.0126; the “Incidence Proportion” that is the cases/population ratio, in our study 1220/20,000 = 0.061; the “...
In a histogram for which area is proportion, if the width of a bar is 4 and the height is 0.13, and the total population represented in the histogram is 190, then what is the amount of population represented by the bar? Construct the frequen...
