Development and validation of the symptom assessment scale for patients with nasopharyngeal cancer undergoing radiotherapy.
Article in Asia-Pacific journal of oncology nursing, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objective: This study aims to develop the Symptom Assessment Scale for Patients with Nasopharyngeal Cancer Undergoing Radiotherapy (SAS-NPC), based on the Symptom Experience Model. Methods: In Phase 1, a content analysis of the literature and group discussions were conducted to construct an initial pool of 61 items. Following expert review by 16 specialists and cognitive interviews with 10 patients, the pool was refined to 56 items. In Phase 2, a convenience sampling method was used to recruit 625 patients with nasopharyngeal cancer (NPC) undergoing radiotherapy, who assessed and explored the scale items. Phase 3 focused on evaluating the scale's reliability and validity. Results: The SAS-NPC consists of 7 dimensions and 33 items. Reliability analysis revealed a Cronbach's α coefficient of 0.928 for the total scale, a split-half reliability of 0.790, and a retest reliability of 0.828. Validity analysis showed content validity indices for each item ranging from 0.833 to 1.000, with an overall content validity index of 0.970 for the scale. Exploratory factor analysis (EFA) identified 7 common factors, which accounted for 74.505% of the total variance. Confirmatory factor analysis (CFA) demonstrated good overall model fit. Conclusions: The SAS-NPC comprehensively captures acute and long-term symptoms associated with patients with NPC undergoing radiotherapy. The scale exhibits strong reliability and validity, making it an ideal tool for assessing NPC symptom burden and facilitating clinical symptom management.
