This quantitative study has a calculated margin of error of 14.43% on the total sample. The measurement was carried out with a 1/10 sample reduction and was verified through qualitative methods and peer review. However, the figures are based on the results that the used tool permits, and it is not possible to achieve a higher degree of reliability due to the impossibility of meeting the temporal, material, and personnel requirements necessary to verify every result that this database records.
