Multiple sexually transmitted infections (STIs) have threatened human health for centuries. Most STIs spread not only through sexual (horizontal) transmission but also through mother-to-child (vertical) transmission. In a previous work (Ito et al. 2019),
Objective: The aim of study is to introduce method of Soft Independent Modeling of Class Analogy (SIMCA), and to express whether the method is affected from the number of independent variables, the relationship between variables and sample size. Study Design: Simulation study. Material and Methods...
In multivariate Cox analysis, age, grade, distant metastasis, number of positive lymph nodes, and tumor size were independent prognostic factors. One (p = 0.926, 1.028 [0.580–1.820]) or two (p = 0.082, 1.399 [0.958–2.043]) positive lymph nodes did not pose additional compromise ...

Monte Carlo methods provide approximate numerical solutions to problems that would be difficult or impossible to solve exactly. The defining characteristic of Monte Carlo simulations is the use of multiple independent trials, each driven by some stochastic (random) process. The results of th...
