the abstract, start to end

estimated treatment differences were -6.91 mmol/mol (95% confidence interval [CI] -8.18; -5.64) and -5.30 mmol/mol (95% CI -6.58; -4.03),

were lower versus degludec (rate ratio 0.48 [95% CI 0.35; 0.68]; P < .0001), but higher versus liraglutide (rate ratio 37.58 [95% CI 19.80; 71.31];
