Position: Clinician Reviewer (Independent Research Reviewer)
Study: VI-SIGNAL-001 — Research Validation of a Non-Diagnostic Facial Scan, Guided Video, and Questionnaire-Based Pattern Detection System
Sponsor: Vi Signal Inc.
Engagement: Part time, remote, consultancy basis (case volume as assigned)
Honorarium: ₹1,500–3,000 per hour

About the Study
VI-SIGNAL-001 is a remote, app-based, non-interventional and non-diagnostic research validation study. It evaluates the agreement between a system's non-diagnostic pattern outputs and independent, clinician-derived research reference labels applied to the same participant-provided data (facial images, guided facial video, and questionnaire responses). The study does not provide medical diagnosis, treatment, or advice to participants.
Role Summary
The Clinician Reviewer independently and blindly reviews assigned, coded participant cases and assigns structured research reference labels for each predefined pattern category, in line with the study's approved reference-label definitions.



These labels form the reference standard against which the system's outputs are validated. The pattern categories are predominantly systemic conditions with facial signs (for example diabetes, jaundice, anaemia, thyroid, dehydration), alongside some dermatological patterns. The role is research-only and involves no clinical care, diagnosis, or contact with participants.
Key Responsibilities
Review assigned coded cases (facial images, guided video, and questionnaire responses) through the secure study portal.
Assign a structured research reference label (Present / Absent / Not assessable) for each predefined pattern category, using only the approved response options and definitions.
Work independently, and remain blinded to system-generated outputs and to other reviewers' assessments at all times.
Select “Not assessable” where image quality or available information does not allow a reliable determination.
Apply the labelling criteria consistentl
