Data were entered into the Palisade @risk® software version 8.2.00172.0 (Palisade Company, LLC) Excel sheet containing three attributes, the parameter number, parameter description, source of the data, and their probability/proportion or the number of parameters required. The obtained information was entered into a specific row and column with their minimum, most likely and maximum values of probability or proportion with a respective probability distribution for continuous and discrete data. Risk Pert and Risk Uniform were the only function distributions used for continuous variables, while risk poisson, risk binomial, and risk in uniform were used for discrete variables. Information from the questionnaire surveys was entered into IBM statistical package for the social sciences (SPSS) statistics version 21 (IBM Corp., NY, USA) and coded for descriptive statistical analysis. The obtained secondary data were both used to formulate a model parameter input description and risk assessment model.

Data were presented as the mean ± standard deviation or median (interquartile range [IQR]) depending on the normality of distribution. Student’s t-test and analysis of variance (ANOVA) were used for parametric analysis. Comparison of means was done using independent samples t-test. Correlation between two parameters was assessed using Pearson coefficient. Statistical significance was considered when P < 0.05. Statistical analysis was done using IBM Statistical Package for the Social Sciences (SPSS) Statistics Version 21 (IBM Corp., Armonk, NY, USA)
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
