Cochrane Australia and the National Covid-19 Clinical Evidence Taskforce have much to reflect on and celebrate this World Evidence-Based Health Care Day. Held on 20 October, this annual global event highlights the need for better evidence to inform health care, and recognises the efforts of hard-working researchers, policymakers, clinicians and health workers everywhere.

It is with great sadness that we mark the passing of Chris Del Mar AM, Professor of Public Health at Bond University and one of Australia’s most prolific and generous Cochrane contributors.
