Nutritional Support for Treatment Continuity and Survival in Advanced Gastric Cancer: A Propensity Score-matched Study.
Article in In vivo (Athens, Greece). 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
BACKGROUND/
aimThis study aimed to clarify the effect of nutritional support in patients with advanced gastric cancer (AGC) receiving first-line chemotherapy. PATIENTS AND
methodsWe retrospectively reviewed the medical records of consecutive patients with unresectable or recurrent AGC treated with first-line chemotherapy at Nagoya Medical Center between 2007 and 2024. Patients who received nutritional support were compared with those without nutritional support. Nutritional support included individualized dietary counselling, assessment of energy and protein requirements, and multidisciplinary evaluation. Propensity score matching (PSM, 1:1) was applied to adjust for baseline nutritional and inflammatory status. The primary endpoint was time to treatment failure (TTF). Subgroup analyses were conducted by baseline albumin level.
resultsAmong the 324 eligible patients included in the analysis, 76 received nutritional support. Before PSM, patients who were provided nutritional support more frequently presented with poor nutritional profiles. After PSM (n=46 per group), the median TTF was 5.0 months in patients without nutritional support and 4.6 months in those with it. In patients with hypoalbuminemia (albumin <3.5 g/dl), nutritional support significantly prolonged TTF. Finally, multivariate analysis in the pre-PSM cohort identified nutritional support as an independent predictor of TTF.
conclusionAlthough nutritional support was not associated with significant TTF improvement in the overall AGC population after propensity score matching, it emerged as an independent predictor of treatment continuity in multivariate analysis of the pre-PSM cohort. This benefit was particularly evident in patients with hypoalbuminemia, indicating that targeted nutritional intervention is essential for this vulnerable subgroup to prevent premature treatment failure.
