In a previous blog, I discussed the implication of communicating mortality risk to patients with a fracture. In this article, we put forward the new concept of “skeletal age” to quantify the impact of fracture on mortality.
It is easy to determine the chronological age of an individual. The number…
People like me who work in clinical research are no strangers to noise because we deal with this issue almost daily. However, I still very much enjoy reading “Noise — a flaw in human judgment” [1] by Daniel Kahneman, Olivier Sibony, and Cass Sunstein [2]. …
That is what our Prime Minister Scott Morrison said, and I totally agree with his view. It is time to think of an exit strategy from lockdown.
Last weekend, there were mass protests on anti-lockdown across Australia. …
With Steve, I have a lot of memories that go back 30 years. In the early 1990s, when I joined Professor John Eisman’s group working in the Dubbo Osteoporosis Epidemiology Study, John showed me a list of work that I should read, and Steve’s papers were on the top of…

I must admit that I have been increasingly uncomfortable with the ongoing…
A friend of mine is hesitant to take an AstraZeneca (AZ) jab, because he believes that the vaccine is less effective and has higher risk of blood clot than Pfizer’s mRNA vaccine. He is not alone, many Australians, including the educated ones, hold the same view. I beg to differ…
You bet. Health authorities and experts keep reminding us that delta variant represents the ‘greatest threat’ to the nation’s effort of eliminating Covid-19. Some experts even warned us that the Delta variant is deadlier than the original Alpha variant. …
I am an executive member of the Asia Pacific Consortium on Osteoporosis (APCO), a non-profit organization that aims at developing solutions to osteoporosis care in the Asia Pacific region. In this blog entry, I explore the relationship between osteoporotic fracture and mortality that is not widely appreciated in the medical…
The unfortunate post-vaccinated death of a 48 yr old woman last week has raised concerns about the safety of the AstraZeneca vaccine (Vaxzevria). Here, I offer my interpretation of the risk in terms of micromort, and then my analysis of risk and benefit of the vaccination program.
Quantifying risk in…
