Impact of unmet needs on health-related quality of life among cancer survivors in Ulsan, Korea.
Article in BMC cancer, 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
backgroundCancer survivorship care emphasizes biomedical interventions, but psychological and social difficulties remain underaddressed. This study aimed to (i) quantify the association between unmet needs and quality of life (QOL), and (ii) evaluate whether these associations are consistent across two health-related QOL (HRQoL) instruments among cancer survivors.
methodsCross-sectional survey of adults (≥ 19) in Ulsan, Korea (2021, 2022). HRQoL (EQ-5D-5 L; EORTC QLQ-C30) was related to unmet-need domains using multivariable linear regression adjusted for prespecified sociodemographic and clinical covariates (gender, age, cancer type/stage, education level, household size, household monthly income, smoking status, alcohol consumption). Statistical analyses included Student's t-tests, one-way ANOVA, and multivariable linear regression.
resultsAfter excluding cases with insufficient information, 372 survivors were analyzed. EQ-5D-5 L utility was negatively associated with age ≥ 60 years (B=-0.04, 95%CI[-0.07, -0.01]), advanced cancer stage (Stage IV: B=-0.11, 95%CI[-0.14, -0.07]), unmet psychological needs (B=-0.09, 95%CI[-0.13, -0.06]), and unmet financial needs (B=-0.04, 95%CI[-0.09, -0.001]). On the EORTC QLQ-C30, advanced cancer stage showed negative associations with the functional scale (Stage IV: B=-14.87, 95%CI[-18.65, -11.10]) and positive associations with the symptom scale (Stage IV: B = 9.01, 95%CI[6.44, 11.57]). Higher household income (B = 4.99, 95%CI[1.71, 8.26]) was positively associated with the functional scale, while unmet psychological needs were negatively associated with the functional scale (B=-5.96, 95%CI[-10.04, -1.89]) and positively associated with the symptom scale (B = 8.80, 95%CI[6.04, 11.57]).
conclusionsUnmet psychological needs showed the most consistent associations with poorer HRQoL across both generic and cancer-specific instruments. Unmet financial needs showed weaker but directionally consistent associations, and the concurrent use of both instruments provided complementary perspectives on survivorship-related quality of life.
