Primary

MeasureTime frameDescription
Accuracy evaluation1 month post-op3D superposition of post-operative volumetric CT and the digital therapeutic project files. The variables and parameters analysis will be performed after the data distribution analysis, using the D'Agostino Pearson omnibus normality test: normal distribution data will be expressed as mean and standard deviation; non-normal distribution data will be expressed as median and interquartile range. The quantitative and qualitative variables will be expressed in terms of absolute frequencies and percentage value. Image superposition accuracy will be defined by measuring distances between the different anatomical reference points, considering excellent accuracy for distances less than 2 mm. Correlation and multivariate analysis models will be developed to define the secondary outcomes.
