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 and test the self-management instrument for breast cancer patients undergoing adjuvant therapy (SMAT-B). Methods: After a qualitative interview with 29 patients and two rounds of Delphi expert consultation with 15 experts, 49 items were initially generated. Before item reduction, another structured interview was conducted for content validity. Item analysis and exploratory factor analysis ( Results: The final version of SMAT-B includes 7 dimensions and 31 items after item reduction. The testing results suggested that SMAT-B had good internal consistency (Total Cronbach's α = 0.952), good split-half reliability (Spearman-Brown coefficient = 0.904), good stability (Total intraclass correlation coefficient = 0.797), acceptable measurement error (SEM = 5.28), and acceptable construct validity (Standardized root mean square residual = 0.055). The hypotheses of construct validity were all verified to a certain extent ( Conclusions: The 31-item SMAT-B, developed in interviews with patients and consultation with experts, demonstrated good psychometric properties and can be recommended for researchers and clinicians for further validity testing and evaluation of the self-management ability of breast cancer patients. Trial registration: ChiCTR2100052868.
