Health Safety Signals
by x402Pulse in Other
Drug safety signal detection (pharmacovigilance) from FDA FAERS: side effects reported disproportionately often with a drug versus all other drugs, using the proportional reporting ratio (PRR) and chi-square with standard Evans criteria. A statistical prompt for study, not evidence of harm. Not medical advice.
