Factors associated with functional status among older adults with colorectal cancer receiving chemotherapy in Thailand: A cross-sectional study.
Article in Belitung nursing journal, 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
Background: Older adults with colorectal cancer who undergo chemotherapy are at high risk of functional status decline. Various demographic and physiological factors influence functional status. However, based on the Theory of Unpleasant Symptoms, few studies have examined the relationships among physiological, psychological, and situational factors, symptom experience, and functional status in older adults with colorectal cancer undergoing chemotherapy. Objective: This study aimed to describe functional status and investigate its associated factors among older adults with colorectal cancer undergoing chemotherapy in Thailand. Methods: A cross-sectional study was conducted among 128 older adults with colorectal cancer receiving chemotherapy. Participants were recruited from a cancer hospital in Northeastern Thailand using multi-stage sampling, followed by systematic random sampling with a random digit table. Data were collected between October 2024 and July 2025 using standardized instruments. Data were analyzed using descriptive statistics, Pearson's product-moment correlation coefficients, and multiple regression analysis. Results: The findings revealed that participants' functional status was moderate. Pearson's correlation coefficient analysis showed that body mass index and social support were positively associated with functional status. Fatigue, depression, and the number of chemotherapy cycles were negatively associated with functional status. Multiple regression analysis showed that fatigue was the strongest factor negatively associated with functional status ( Conclusion: These findings suggest that nurses should implement early screening and proactive nursing interventions to reduce fatigue and depression. Such interventions may include optimizing nutritional status at each chemotherapy cycle and providing family support to help this population preserve functional status.
