A step-wedged cluster randomized trial, carried out in six villages in Tumbes, Peru, with 2,376 participants, demonstrates population-wide reductions in blood pressure, which appear to be higher in individuals with hypertension, as well as reductions in risk of hypertension by around 50% for those without hypertension at baseline, after community-wide replacement of regular salt with a potassium-enriched alternative.
