  "summary": "This article describes a protocol for a WHO-commissioned systematic review of human observational studies on radiofrequency electromagnetic fields (RF-EMF) and cancer risk. The review plans to evaluate near-field head-localized exposure from wireless phone use, far-field environmental exposure from fixed-site transmitters, and occupational RF exposures. It outlines planned search strategies, a tailored OHAT risk-of-bias tool, and GRADE-based confidence assessment, but provides no findings.",
  "key_points": [
    "The paper is a protocol for a systematic review of RF-EMF exposure and cancer risk in humans.",
    "It is commissioned by the WHO as part of an ongoing project assessing potential health effects of RF-EMF.",
    "Eligible designs include cohort and case-control studies in general and working populations.",
    "Exposures are grouped into wireless phone use (near-field head-localized), fixed-site transmitters (far-field whole-body), and occupational RF sources (near/far-field).",
    "The review will focus on selected tumor types including CNS tumors, salivary gland tumors, and leukaemias depending on exposure category.",
    "Risk of bias will be assessed using a tailored OHAT tool and confidence in evidence will be evaluated using GRADE.",
    "Meta-analysis is planned when appropriate, otherwise narrative synthesis with structured tabulation will be used."
