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
purposeNutritional status and dietary antioxidant capacity are important determinants of clinical resilience in cancer; however, data in hematological malignancies remain limited. We aimed to compare nutritional status, dietary total antioxidant capacity (DTAC), and dietary diversity between patients with newly diagnosed hematological malignancies and healthy controls.
methodsThis case-control study included 34 patients with newly diagnosed hematological malignancies (12 lymphoma, 11 leukaemia, 11 multiple myeloma) and 34 age- and sex-matched healthy controls aged 18-65 years. DTAC was estimated using the ferric reducing antioxidant power (FRAP) method based on a validated food frequency questionnaire. Nutrient intakes and the dietary diversity score (DDS) were derived from 3-day dietary records. Nutritional status was assessed using the Global Leadership Initiative on Malnutrition (GLIM) criteria, along with fat-free mass index (FFMI), and mid-upper arm circumference (MUAC).
resultsPatients had significantly lower DTAC levels than controls (3.85 ± 1.58 vs. 8.68 ± 3.21 mmol/day, p < 0.05). According to GLIM criteria, 35.3% of patients had moderate malnutrition and 26.5% had severe malnutrition, A declining trend in DTAC was observed with worsening malnutrition (p = 0.034), although this did not reach the significance threshold after multiplicity adjustment. Low muscle mass was more prevalent in patients as assessed by both FFMI and MUAC. Energy, protein, zinc, vitamin E, and folate intakes were significantly lower in patients (all p < 0.05), whereas DDS did not differ (p > 0.05). DTAC was positively correlated with intakes of coffee, whole-grain bread, green vegetables, citrus fruits, and fresh fruit (p ≤ 0.05).
conclusionsSignificant differences in nutritional status and DTAC between patients and healthy individuals suggest that suboptimal dietary patterns may accompany hematological malignancies at diagnosis. These findings highlight the potential importance of adequate macro- and micronutrient intake; however, further prospective studies are needed to determine whether targeted nutritional interventions can improve clinical outcomes or contribute to long-term risk reduction.
