What about kidney function? Well Lilly snuck this in the appendix but I still continue to have questions! Both the 9mg and 12mg dose increased Cys-C eGFR by about 4ml/min. Modest decrease in UACR but baseline was low. Show us the full renal data from Transcend CKD Lilly. PLEASE. #NephJC

At 12-month follow-up, primary outcome data were available for 846 (90%) patients. Treatment failure occurred in 153 (34%) of 452 patients in the antibiotic group, compared with 28 (7%) of 394 in the appendicectomy group (difference 26·7%, 90% CI 22·4–30·9).
