Many scoring systems are used to evaluate malnutrition, but there is no consensus on which scoring system would be more appropriate. We aimed to investigate the effect of malnutrition in patients with non-valvular atrial fibrillation (NVAF) and to compare three scoring systems. A total of 2592 patients with non-valvular AF from 35 different centers in Turkey were included in this prospective study. All participants were divided into two groups: 761 patients who died and 1831 patients who were alive. The malnutrition status of all participants was evaluated with three scoring systems. The primary outcome was all-cause mortality. The mean age of the population was 68.7 ± 11.1 years, and 55.5% were female. According to Cox regression analysis, the geriatric nutritional risk index (GNRI) (HR=0.989, 95% CI: 0.982-0.997, p=0.007), controlling nutritional status (CONUT) score (HR=1.121, 95% CI: 1.060-1.185, p
