Based on Pearl's growth rate equation and diffusion theory, a SHT completeness variable is introduced to model the microstructural evolution of the material during the SHT period.
Because we utilized data from another source document (and did not generate the information prospectively), we evaluated their quality by creating an informational completeness variable, adapting recommendations given for the evaluation of information systems published by the Centers for Disease Control and Prevention, United States [14].
Although not all variables in ED SS exhibit high levels of completeness, key variables, such as date and time of visit, sex, age, chief complaint, and zip code of residence, have high percentages of completeness.
The reserved datasets will be chosen on the basis of completeness of variables collected so that, we hope, all the variables present in the final model will also be in the reserved datasets, thus requiring no or minimal modification of the final model for external validation purposes.
The validation process significantly improved the completeness of variables and the quality of the ASR data.
There were small or no risks associated with residential region and socioeconomic status in the overall invasive EOC, but, for completeness, these variables were still included in the model although their exclusion did not alter risks associated with the other variables.
Response rates to the questionnaires decreased over time, from 100% at baseline to 67% at 2 weeks postnatal, and 58% at 6 weeks postnatal (Supporting Information Table S3, Questionnaire response rates) with a concomitant reduction in data completeness for variables assessed at those time-points.
By linking different data sources according to study objectives, study variables can be increased and the completeness of the variable values can be improved significantly [ 10, 26].
Next, Pearson's correlation coefficient was used to reveal the correlations between the independent variables and the outcome variables (completeness, fidelity, intention to continue using current LLL and intention to adopt new LLL).
This clustering is probably not a bias of the variable completeness of the historical catalogues.
Depending on the neurological level of injury and completeness, SCI causes variable patterns of muscle spasticity and weakness.
