Development, Rasch analysis and validation of the kidney symptom burden questionnaire (KSB-Q).
Article in Clinical kidney journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Increasingly, patient-reported outcome measures (PROMs) are used to monitor chronic kidney disease (CKD) symptoms in routine clinical practice. However, such symptom measurement currently requires completion of multiple, often lengthy, PROMs, which may lead to questionnaire fatigue, lower levels of completion, and missing data. Moreover, many CKD-specific PROMs lack evidence of important measurement properties and few were developed using contemporary psychometric methods. The study objective was to develop and validate a short-form kidney symptom burden questionnaire (KSB-Q). Methods: A cross-sectional item pool survey was distributed to adults (≥18 years) with CKD stages 3-5 [including individuals not receiving kidney replacement therapy (KRT), those receiving dialysis and those with a functioning kidney transplant] in England (Birmingham, London, Sheffield, and Nottingham) from March to September 2022. Rasch measurement was used to assess the psychometric properties of the item pool. Cognitive debriefing interviews were conducted to evaluate content validity. Results: In total, 419/1464 participants responded (29% response rate), with 28% receiving dialysis and 30% in receipt of a kidney transplant. Rasch analysis indicated that nine items, one for each of nine symptom domains (fatigue, pain, memory/concentration, poor sleep, skin problems, gastrointestinal problems, dizziness, restless legs, and shortness of breath), formed a PROM with strong psychometric properties (including statistically acceptable reliability, test-retest reliability, and validity). Cognitive debriefing and survey responses confirmed content validity encompassing relevance, comprehensiveness, and clarity. Conclusions: The KSB-Q is a nine-item PROM measuring somatic symptoms. The KSB-Q demonstrates strong psychometric properties in patients with CKD stages 3-5, including those not receiving KRT, individuals receiving dialysis, and those with a functioning kidney transplant.
