d have the same odds ratio = 44.
Equal differences in percentages means that the same proportion of
the population changed their minds.
The meaning was probably "proportionate" = "of the same order of
magnitude".

I remember I read somewhere about different effect size measures
and now I found the spot: A book by Michael Oakes, U. of Sussex,
"Statistical Inference" 1990. The measures were (xbar-ybar)/s,
Proportion misclassified, r squared (biserial corr) and w squared
(which I think means the same as Rs
re on a scale which is arbitrary, not meters or
USDs, let's say you have constructed a scale from multiple items.
How do you define effect size? How can differences between means
be interpreted to be informative?
