Will hopefully know more about phosphate levels soon from the ongoing PHOSPHATE trial.

Unfortunately no. We tried to look for that based on the ACHIEVE results but the outcomes were poorly reported by sex in most trials included in the meta-analysis.

Not 100% sure (been awhile since I signed off on any enrolment forms for ACHIEVE), but I don't recall race/ethnicity being recorded.

You got it. Pragmatic choice.
Equivalent dose in ESRD to that used in CV studies.
Most common dose used in prior trials in ESRD.

The updated meta-analysis will be published very soon along with ACHIEVE.

I do think expecting anything to improve all-cause mortality in ESRD is probably unwise.
