During 1943–44, the UK’s Medical Research Council (MRC) ran the first modern double-blind trial in the general population, testing patulin (from Penicillium patulinum) for the common cold. This was an important milestone in the development of evidence-based clinical research. 🔬
Led by Sir Harold Himsworth and supported by statisticians M. Greenwood and W. J. Martin, the nationwide study involved over a thousand British office and factory workers — an extraordinary effort during wartime.
🧪 The trial maintained strict blinding: neither the doctors nor the patients knew which treatment was administered. Allocation followed a systematic alternation process overseen by nurses, which was considered a form of effective randomization at the time.
Although the results showed no protective effect of patulin, this pioneering study established the foundation for modern randomized controlled trials (RCTs), setting new standards in transparency and scientific rigor. 🔍
