Low BMI, BMC and BFMI were identified as risk factors for the presence of malnutrition (BMI, p = 0.019; BCMI, p = 0.035; BMC, p = 0.014; BFMI, p = 0.007; extracellular water, p = 0.026), suggesting that they would predict the long-term nutritional status of CD patients treated with anti-TNF therapy. Here, TNF is linked to malnutrition.
