Development and validation of a nutritional literacy assessment scale for nasopharyngeal carcinoma patients undergoing concurrent chemoradiotherapy.

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: Nasopharyngeal carcinoma (NPC) is a head and neck malignancy highly prevalent in East and Southeast Asia, for which concurrent chemoradiotherapy (CCRT) is the standard treatment option. However, the superimposed effects of radiotherapy (especially head and neck radiotherapy) and chemotherapy often lead to severe acute toxic reactions, insufficient nutritional knowledge of patients, and dietary misconceptions all affect the patient's ability to eat and their nutritional status. Therefore, there is an urgent need to develop a Nutritional Literacy Scale (NLS) for patients undergoing simultaneous radiotherapy and chemotherapy for nasopharyngeal carcinoma (NPC) to optimize the overall nutritional management of NPC patients and to improve the therapeutic effect. Methods: The first draft of the scale was formed through literature analysis, semi-structured interviews, and expert correspondence. From April 2024 to December 2024, 245 patients with nasopharyngeal carcinoma treated with simultaneous radiotherapy and chemotherapy in the radiotherapy department of the First Affiliated Hospital of Guangxi Medical University were collected as the study subjects, and the scale was subjected to item analysis and reliability and validity tests, and the questionnaire was administered again to the patients 2 weeks later to measure the re-test reliability of the scale. Results: The Nutritional Literacy Scale for Nasopharyngeal Carcinoma Patients Undergoing Simultaneous Radiotherapy included 4 dimensions and 30 entries. Exploratory factor analysis extracted four male factors with a cumulative variance contribution of 62.3%; validated factor analysis showed that χ Conclusion: The Nutritional Literacy Scale for Nasopharyngeal Cancer Patients Undergoing Simultaneous Radiotherapy has good reliability and validity.
