Authors Retract Study On Hydroxychloroquine

A study on chloroquine, published in The Lancet, was retracted due to data audit issues. The data, sourced from Surges Sphere Corporation, was found unreliable, leading to retractions in other journals. This prompted the WHO to temporarily halt hydroxychloroquine testing, though it has since resumed. President Trump has promoted the drug as a COVID-19 treatment, despite FDA warnings about its risks.
