Re: Incidence rates

I thank Gupta & Sehgal for their rapid response[1] to my endgame on incidence rates[2]. Unfortunately the significance of their rapid response was not intuitively obvious. Nonetheless, it would appear they have misread the endgame. In particular statement a) “An incidence rate represents the proportion of women who experienced hip fractures” was stated as “false”, and not “true” as Gupta & Sehgal would appear to be suggesting.
