Intake and Nutritional Adequacy in Patients With Cancer Diagnosed With Malignant Bowel Obstruction: A Secondary Analysis of a Randomized Trial.
Trial report in Journal of the Academy of Nutrition and Dietetics, 2025. 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
backgroundMalignant bowel obstruction (MBO) is experienced by many with advanced cancer. Patients with MBO cannot eat and may have reduced ability to eat once the acute process has resolved. Sparse data exist to describe oral intake capacity and adequacy of nutrition in patients with MBO. These data are critical to developing effective supportive care nutrition therapy for patients with MBO.
objectiveThe aim of this study was to describe the ability to consume food and liquids orally, estimating nutritional adequacy of diet in a sample of patients who received surgical or nonsurgical treatment for MBO.
designA descriptive secondary data analysis of repeated dietary intake measures from S1316, a pragmatic comparative effectiveness trial of surgical and nonsurgical treatment for MBO. Participant enrollment occurred between 2015 and 2020. Ability to eat was assessed through self-reported telephone survey and intake was estimated using telephone-based 24-hour recalls, applying US Department of Agriculture multipass methodology. PARTICIPANTS/
settingThe primary trial was conducted within the SWOG Cancer Research Network and included recruitment sites across the United States and Latin America. Eligible participants were diagnosed with, and hospitalized for, MBO.
main outcome measuresThe main outcomes measures were self- or caregiver-reported ability to eat, as well as overall nutrient intake. STATISTICAL ANALYSIS: Descriptive statistics were used to report patient characteristics, intake, and nutrient adequacy. Nutrient intake was presented by tertiles of gastrointestinal symptom severity and assessed.
resultsTwo hundred twenty-one participants were registered; 199 were eligible and included. At week 1, 51% of patients with MBO reported consuming some solid food orally; 34% reported no oral intake; and 13% were on enteral feeding only. For patients alive and responsive to recalls at 13 weeks (n = 57), 82% (n = 47) reported consuming solid food. Compared with recommendations, mean reported intake was inadequate for most nutrients.
conclusionsOral intake is reported in more than one-half of patients diagnosed with MBO. Medical nutrition therapy should be tailored to patient's tolerance for eating and with consideration or patient's desire to address nutritional inadequacies.
