Development and Psychometric Validation of BREAST-Q Scales Measuring Cancer Worry, Fatigue, and Impact on Work.
Article in Annals of surgical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundThe BREAST-Q is a patient-reported outcome measure for women with breast cancer. The aim of this study was to develop new BREAST-Q scales to measure Cancer Worry, Fatigue and Impact on Work.
methodsData were collected between January 2017 and November 2019. Phase 1 (qualitative) included participants from Canada and the USA, pre/post any type of breast cancer treatment (surgery, adjuvant, neoadjuvant). Interviews were audio-recorded, transcribed verbatim and coded line-by-line. New scales were drafted and refined through cognitive interviews and expert input. Phase 2 (field-test study) involved USA members of the Love Research Army (LRA). Rasch measurement theory analysis was used to examine reliability and validity.
resultsIn phase 1, 57 women were interviewed. Three concepts were identified as important to the breast cancer experience that are not currently covered in the BREAST-Q and developed into scales, i.e., Cancer Worry, Fatigue and Impact on Work. Feedback from nine women and 23 experts was used to establish content validity. The scales were field-tested in the LRA sample (n = 1680), of whom 1006 completed a test-retest. Reliability was > 0.81 for the person separation index, > 0.89 for Cronbach's alpha and > 0.83 for interclass correlation coefficients. Lower scores on all three scales were significantly associated with being closer in time to diagnosis and having a higher cancer stage at diagnosis (p < 0.001 on ANOVA).
conclusionThese new scales expand the BREAST-Q measurement system and provide a means to evaluate additional important outcomes for breast cancer patients in clinical care and research.
