Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Satisfaction assessed by a 5-points Likert scales about using the application for the monitoring and evaluation of Raynaud's Phenomenon | 2 weeks | The questionnaire assesses different items such as the ease of use of the application, the installation process on the smartphone, the use of reminders, etc. Overall satisfaction will be calculated as the non-weighted average of all items. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Relationship between cutaneous digital temperature assessed by thermography and the frequency of RP attacks | 2 weeks | Correlation between digital temperature and the daily frequency of attacks |
| Relationship between cutaneous digital temperature assessed by thermography and the duration of RP attacks | 2 weeks | Correlation between digital temperature and the cumulative daily duration of attacks |
| Relationship between cutaneous digital temperature assessed by thermography and the severity of Raynaud's Phenomenon | 2 weeks | Correlation between digital temperature and Raynaud's Condition Score (RCS) |
| Effect of Raynaud etiology on thermographic data | 2 weeks | Comparison of cutaneous digital temperature between patients with primary and secondary Raynaud |
| Effect of Raynaud treatment on thermographic data | 2 weeks | Comparison of cutaneous digital temperature between patients treated with calcium channel blockers and untreated patients |
| Relationship between cutaneous digital temperature assessed by thermography and pain during RP attacks | 2 weeks | Correlation between digital temperature and pain during attacks (assessed through a 10-point VAS) |
