Nutritional support for severe malnutrition in newly diagnosed Crohn's disease: a case report.
Article in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Crohn's disease (CD) and ulcerative colitis are chronic inflammatory bowel diseases (IBDs) characterized by relapsing exacerbations related to a dysregulated immune response, resulting primarily in gastrointestinal symptoms and also frequently in signs of chronic systemic inflammation. Malnutrition is a possible complication of IBD with a prevalence ranging from 20 to 85%, varying with disease activity, location, and age, and is recognized as having a multifactorial pathogenesis. Malnutrition in patients with IBD should be diagnosed early and treated appropriately because it can heavily affect patient prognosis, including complications, hospitalization rates, mortality, and overall quality of life. Therefore, patients with IBD should be screened for malnutrition at diagnosis and regularly thereafter. Moreover, assessing micronutrient deficiencies in patients with IBD is recommended ideally during clinical and biochemical remission. We reported the case of a 56-year-old female patient admitted to our department who reported chronic diarrhea for several months, along with recurrent abdominal pain, low-grade evening fever, nausea, hyporexia, and significant involuntary weight loss, with probable sarcopenia. Iron-deficiency anemia, an elevated platelet count, elevated inflammatory markers, and some oligoelement deficiencies were observed on blood tests. A diagnosis of extensive ileo-colonic CD (A3, L3, B1 according to the Montreal classification) complicated by a perianal abscess and simple intrasphincteric fistula, requiring surgery, was made during the hospitalization. As agreed with our nutritional team, given the severe malnutrition observed in patients at risk of refeeding syndrome, the patient received thiamine supplementation, minimal enteral feeding with oral nutritional supplements (ONS), and simultaneous parenteral nutrition with a ternary emulsion supplemented with vitamins and trace elements. Parenteral nutritional supplementation and ONS were continued for 2 months after discharge to improve the patient's nutritional status. Subsequently, the patient was able to eat only natural foods, as advised by our hospital's nutrition team. Finally, we briefly reviewed recommendations on malnutrition screening and enteral or parenteral nutrition in patients with IBD to reduce morbidity and mortality due to malnutrition.
