Development and validation of a symptom illustration scale from the patient-reported outcome common terminology criteria for adverse events for patients with breast cancer.
Article in Breast cancer (Tokyo, Japan), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeEmojis are commonly used for daily communication and may be useful in assessing patient-reported outcomes (PROs) in breast cancer. The purpose of this study is to develop and validate a Symptom Illustration Scale (SIS) as a new PRO measurement.
methodsEighteen original SIS items were developed from the PRO-CTCAE. In cohort one, the SIS validity and reliability were examined in patients with breast cancer, using a semi-structured five-question survey to investigate content validity. PROs with PRO-CTCAE and SIS were examined twice to determine criteria validity and test-retest reliability. In cohort two, the responsiveness of the scales were examined in patients treated with anthracycline, docetaxel, paclitaxel, and endocrine therapy. PROs with PRO-CTCAE and SIS were investigated two or three times, depending on the therapy.
resultsPatients were enrolled from August 2019 to October 2020. In cohort one (n = 70), most patients had no difficulties with the SIS, but 16 patients indicated that it was difficult to understand severities in the SIS. For criterion validity, Spearman rank correlation coefficients (r
conclusionAn original SIS from the PRO-CTCAE for patients with breast cancer were verified the validity, reliability, and responsiveness. Further studies to improve and validate the SIS are needed.
