  "summary": "This article presents a protocol for a systematic review of human observational studies assessing whether longer-term or repeated RF-EMF exposure is associated with tinnitus, migraine, headaches, sleep disturbances, and composite symptom scores. The protocol follows WHO guideline-development methods and plans risk-of-bias assessment using an adapted NTP-OHAT tool and certainty grading using an OHAT GRADE-based approach. No findings are reported because this is a protocol.",
  "key_points": [
    "The protocol targets RF-EMF exposures from 100 kHz to 300 GHz and focuses on symptoms reported at low exposure levels below regulatory limits (as context).",
    "Eligible studies are peer-reviewed cohort, case-control, and panel studies in the general population or workers with RF-EMF exposure lasting at least one week.",
    "Primary outcomes include tinnitus, migraine, headaches, sleep disturbances, and composite symptom scores.",
    "The search will include multiple databases (e.g., Medline, Web of Science, PsycInfo, Cochrane Library, Epistemonikos, Embase) plus EMF-Portal and reference checks.",
    "The review plans separate analyses for local exposure, far-field exposure, and occupational exposure.",
    "Risk of bias will be assessed using an adapted NTP-OHAT tool for observational RF-EMF studies, and certainty will be rated with an OHAT GRADE-based approach.",
    "The protocol is part of a larger WHO effort comprising multiple systematic reviews on RF-EMF health effects and is registered in PROSPERO (CRD42021239432)."
