Feasibility of using Simple Diet Self-Assessment Tool (SDSAT) to explore patterns of dietary intake for patients undergoing chemotherapy.
Article in Nutrition journal, 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
backgroundChemotherapy is often accompanied by impaired dietary intake, which is linked to poor clinical outcomes if not effectively addressed. Predicting dietary changes can facilitate early nutritional support, but the dynamic patterns and interindividual variability in dietary intake during chemotherapy remain unclear. Our aim was thus to evaluate the feasibility of using the Simple Diet Self-Assessment Tool (SDSAT) to establish dietary intake patterns in patients undergoing chemotherapy.
methodsThis is an ongoing, prospective cohort study. Patients receiving chemotherapy from the Cancer Hospital, Chinese Academy of Medical Sciences were enrolled. Diet was assessed using the SDSAT once before the treatment and at least three times during one chemotherapy cycle. We applied a group-based trajectory model to identify trajectories of dietary intake. The 24-hour dietary recall (24HR) was used to verify the validity of energy and protein intake estimated by SDSAT; compliance with SDSAT was also assessed.
resultsFive trajectory groups were identified for food intake based on 217 chemotherapy cycles by 56 patients. The compliance rate accounted for 81.11% for 4 cumulative responses per cycle. The agreement between the SDSAT score and the dietary energy and protein intake estimated from 24HR was high (κ: 0.888–1.0, P < 0.001). Groups 1 and 2 had significantly lower dietary energy/protein intake than Groups 4 and 5 (P < 0.001) but with distinct dietary patterns. Group 4 was the most common dietary trajectory (35.10%). Furthermore, Groups 1, 2, and 3 had significantly weaker handgrip strength (OR: 1.10, 95% CI: 1.01–1.19, P = 0.031) compared with Groups 4 and 5.
conclusionsSDSAT can be used to establish dietary trajectories during one chemotherapy cycle. Longitudinal analysis highlights the interindividual differences in dietary intake patterns among patients receiving chemotherapy and may help to inform proactive and individually tailored nutritional interventions.
