Yontemler: ROC yontemi yerine onerilen LOWESS
yontemi, karmasik iliskileri bir regresyon denklemiyle ifade etmek yerine daha cok gorsel bir ifade icin tercih edilir.
Since none of the predictors were significantly associated with the RWG and the DRT in a multivariable model, except for HIV disease stage, a multivariate LOWESS
regression (MLOWESS) was not necessary to determine the adjusted relationship between the two outcome variables.
Figure 2 plotted using LOWESS

Although there were no obvious trends visually observable in the association between volume/specialization and risk-adjusted mortality, both the LOWESS
curves and least-squares lines suggest slight downward-sloping trends, indicating lower than expected mortality rates being associated with increased volume or specialization.
Through the data shown in Figure 1 I have also added a Lowess
trend line, which provides a locally weighted estimate of how the data are shifting.
