The experimental model contains a collection of variables of the cutting process by means of sensors and transformation of those data into numerical values, which are a starting point for data calculation of characteristic coefficients of materials.
The design of the database has been conceived in a user-friendly way with additional possibilities for its further use, such as: statistical analysis of the data, calculation of safety indicators, accident reports and human factors analysis.
Indeed, preparation of data, calculation of mixture descriptors, and application of the correct validation protocol require considerable effort and can be prone to error.
The software application allows for collation of data, calculation of scores and development of benchmarks to allow comparisons between healthcare organizations.
Such categorisation of the data (calculation of the period variable and time span) was based on the same assumptions as those discussed in previous studies [ 12, 25- 27].
Statistical analyses to evaluate the distribution of data, calculation of median and interquartile ranges were performed using GraphPad Prism (GraphPad Prism 4 Software, Inc., La Jolla, CA).
Procedures for data processing have been previously described [ 30], including background subtraction, correction for illumination energy, correction for system throughput, and (for reflectance data) calculation of the ratio of tissue reflectance to the reflectance of a white Teflon standard.
This may be due to the fact that the recordings were made in a clinical setting that is not entirely noise-free and this could have interfered with the data calculation of this parameter.
