It really wasn't.
The raw incidence rate ratio (% more women with IPV that develop CFS) was 70% more, compared to 95% more for FM.
That's not what I'd call 'slight'.
However, due to the lower numbers, the 95% confidence bound of CFS increase was almost zero. (1%), whereas for FM it's 54%.
It was slight after the sensitivity analysis where the effect for CFS basically disappeared.
