§1.3Primary endpoint

Time to first occurrence of a composite kidney outcome: onset of persistent 50 % or greater reduction in eGFR, persistent eGFR below 15 mL/min/1.73 m², initiation of kidney replacement therapy, or death from kidney or cardiovascular causes

§1.4Principal result

Hazard ratio 0.76 (95 % CI 0.66 to 0.88); annual eGFR slope difference 1.16 mL/min/1.73 m² per year.[1]

Stopped early for efficacy on the recommendation of its independent data monitoring committee. The Institute records early stopping as a source of modest effect-size inflation and says so wherever the FLOW estimate is reproduced.

§1.5Provenance of this abstract

Table 1. Field-by-field provenance. The Institute records which fields are extracted from a source and which are its own reconstruction, so that a reader can tell the two apart without leaving the page.
