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: To translate and culturally validate the VALue of the UteruS (VALUS) instrument in Brazilian Portuguese language and to identify predictors for VALUS score. Methods: A cross-sectional study (February to November 2024) at a tertiary, academic hospital was performed with 164 women presenting symptomatic uterine fibroids (UF) (n=139) or endometrial polyps (n=25) that underwent hysterectomy or myomectomy/polypectomy. The VALUS instrument was translated and culturally validated first. Psychometric variables (internal consistency, test-retest, discriminant validity) were calculated. Women completed the VALUS instrument prior to the decision-making process to undergo surgery. The Uterine Fibroid Symptoms-Quality of Life (UFS-QOL) was also completed for women with UF. Uni- and multivariate linear regression was calculated to seek for associated factors with the VALUS total score. Results: Women that underwent hysterectomy were older, with higher education, higher parity and frequency of abdominal/pelvic surgeries than the non-hysterectomy group. VALUS scores were statistically higher in the non-hysterectomy for some questions and total score. Internal consistency of the VALUS instrument was excellent (alpha=0.890) and test-retest analysis did not differ between the groups (p=0.891). The UFS-QoL quality of life score presented a negative correlation with VALUS instrument. Multivariate linear regression demonstrated that the presence of abdominal/pelvic surgeries was associated with a lower VALUS score. Conclusion: VALUS demonstrated adequate internal consistency and reliability, but with low discriminant validity for the prediction of hysterectomy versus uterine-preservation in women with UF or endometrial polyps. Presence of abdominal/pelvic surgery is associated with a lower VALUS score.
