Abstract:
Supplementary File 1: R Code and output - Demographic AnalysisThis is a stand alone report containing the code and output of an R script, which was generated by the "Compile Report" function in RStudio (R Statistical Software package (version 3.2.4 (2016-03-10))). This code summarizes the demographic, obstetric, and sleep behaviour of the participants (collected via a questionnaire completed by each participant on her first sleep test) and compares these data between all participants whose first sleep test was PrenaBelt (followed by sham-PrenaB (...)
Supplementary File 1: R Code and output - Demographic AnalysisThis is a stand alone report containing the code and output of an R script, which was generated by the "Compile Report" function in RStudio (R Statistical Software package (version 3.2.4 (2016-03-10))). This code summarizes the demographic, obstetric, and sleep behaviour of the participants (collected via a questionnaire completed by each participant on her first sleep test) and compares these data between all participants whose first sleep test was PrenaBelt (followed by sham-PrenaBelt on the second sleep test) versus all participants whose first sleep test was sham-PrenaBelt (followed by PrenaBelt on the second sleep test).Code and output - Demographic Analysis.docxSupplementary File 2: R Code and output - PSG AnalysisThis is a stand alone report containing the code and output of an R script, which was generated by the "Compile Report" function in RStudio (R Statistical Software package (version 3.2.4 (2016-03-10))). This code processes the polysomnography (PSG) sleep reports in full, making within-participant (paired) comparisons and between-participant (unpaired) comparisons. The sleep reports were generated by Embla Sandman Elite sleep diagnostic software (Natus Medical Incorporated, Pleasanton, USA). The data in the PSG sleep reports was collected via Pro-Tech zRIP Durabelts (Philips Respironics, Murrysville, USA) for respiration, PT1 pressure transducers (BRAEBON Medical Corporation, Kanata, Canada) for airflow and snoring, electrodes (Natus Medical Incorporated, Pleasanton, USA) for ECG/EEG/EOG/EMG, and finger-tip pulse oximetry for peripheral blood oxygen saturation (SpO2) in accordance with the American Academy of Sleep Medicine 2014 guidelines. Audio and video data were also recorded and used in order to determine body position and snoring.Code and output - PSG Analysis.docxSupplementary File 3: R Code and output - Feedback AnalysisThis is a stand alone report containing the code and output of an R script, which was generated by the "Compile Report" function in RStudio (R Statistical Software package (version 3.2.4 (2016-03-10))). This code processes the participants' feedback on the PrenaBelt (collected via a questionnaire completed by each participant after each sleep test). It summarizes these data, completes within-participant (paired) comparison of these data ("before/after"), and completes between-participants (unpaired) comparison of these data (bulk test for differences between all PrenaBelt sleep test nights versus all sham-PrenaBelt nights).Code and output - Feedback Analysis.docxSupplementary File 4: R Code and output - Self-Report Accuracy AnalysisThis is a stand alone report containing the code and output of an R script, which was generated by the "Compile Report" function in RStudio (R Statistical Software package (version 3.2.4 (2016-03-10))). This code compares each participant's perception of her sleep behaviours (collected via a questionnaire completed by each participant after each sleep test) to her polysomnography-determined sleep behaviours (collected via audio and video and Embla Sandman Elite sleep diagnostic software (Natus Medical Incorporated, Pleasanton, USA)) in order to determine the ability of participants to accurately recall their sleep onset position, waking position, number of position changes during the night, and percentage of sleep time in each position.Code and output - Self-Report Accuracy Analysis.docx
