Both studies ask what appears to be the same research question: was there benefit? However, the studies are indeed quite different in what effect they are examining. The study just published looks at whether patients who enrolled in the monitoring programme had improved outcomes over those not enrolled. The previously published study assessed whether this national programme resulted in fewer hospitalisations and deaths in the country. In other words, what was the effect of the programme in reducing adverse outcomes from COVID in England? These are very different questions, and therefore we agreed with the authors on the need to present the findings as two separate papers.
