Accuracy of the Apple Watch Series 4 and Fitbit Versa for Assessing Energy Expenditure and Heart Rate of Wheelchair Users During Treadmill Wheelchair Propulsion: Cross-sectional Study

Accuracy of the Apple Watch Series 4 and Fitbit Versa for Assessing Energy Expenditure and Heart Rate of Wheelchair Users During Treadmill Wheelchair Propulsion: Cross-sectional Study

Interclass correlation coefficients (ICCs) were used to quantify relative agreement between criterion devices and SWs for both EE and HR. The ICCs were calculated using the 2-way random effects model with absolute agreement by using the icc function from the irr package. ICCs were categorized based on widely used cutoff points into poor (0.9) [30,31].

Interrater Agreement on National Institutes of Health Stroke Scale Between Paramedics and Stroke Physicians: Validation Study for the Digital Training Model in the Paramedic Norwegian Acute Stroke Prehospital Project

Interrater Agreement on National Institutes of Health Stroke Scale Between Paramedics and Stroke Physicians: Validation Study for the Digital Training Model in the Paramedic Norwegian Acute Stroke Prehospital Project

To validate the training model, we decided to test the interrater agreement between paramedics and stroke physicians, and we planned for a pilot study. Due to the COVID-19 pandemic, a need for digital training emerged. For practical reasons, we decided to test the interrater agreement after digital simulation training. The validation study took place in Oslo, Norway, in December 2020.

Remote Rating of Atopic Dermatitis Severity Using Photo-Based Assessments: Proof-of-Concept and Reliability Evaluation

Remote Rating of Atopic Dermatitis Severity Using Photo-Based Assessments: Proof-of-Concept and Reliability Evaluation

They reported an excellent agreement between in-person assessment and remote assessment of photographs with respect to body surface area, Eczema Area and Severity Index, and Scoring AD (SCORAD) scales. However, to better accommodate the promises of VCT in which most of the study tasks are conveniently performed on participants' smartphones from the comfort of their own home, the number of photographs required from participants in dermatological trials should be minimized.

Adherence of Mobile App-Based Surveys and Comparison With Traditional Surveys: eCohort Study

Adherence of Mobile App-Based Surveys and Comparison With Traditional Surveys: eCohort Study

To evaluate the agreement of digital survey measures, we compared surveys at e FHS baseline to surveys collected from research center examination 3 using the concordance correlation coefficient (CCC) [23,24] and Bland-Altman plots [25,26]. We used the measurements in the research center as the gold standard for the Bland-Altman analysis. We investigated three different types of surveys deployed at different time intervals: PAI, depressive symptoms surveys (CES-D score), and alcohol consumption surveys.
