Evaluation of the Distress Thermometer in Pelvic Exenteration: Responsiveness-To-Change, Convergent Validity, and Clinical Cutoff.

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
backgroundPelvic exenteration (PE) is a radical surgery for advanced pelvic malignancies that carries substantial psychosocial impacts. Assessing distress is critical for timely support.
aimsTo evaluate the responsiveness-to-change and convergent validity of the distress thermometer (DT), and to determine an optimal cutoff score for detecting clinically significant distress in a PE cohort.
methodsSecondary analyses of cohort study data involving adult patients who underwent PE at a quaternary referral hospital. Responsiveness was evaluated by determining whether the DT differentiated cases of decreased emotional well-being and health-related quality of life from pre- to post-surgery, using the Functional Assessment of Cancer Therapy-General (FACT-G), FACT-Colorectal, and Emotional Well-Being (EWB) subscale as external criteria. Convergent validity was evaluated using the correlation between the DT and the EWB subscale scores. Cutoff scores were examined by reviewing the following indices, using an existing EWB cutoff as an external anchor: sensitivity, specificity, positive/negative predictive values, and clinical utility index (CUI).
resultsThe analysis included 377 patients (mean age: 61 years, 56% male; 41% recurrent rectal cancer). The DT demonstrated responsiveness, with AUCs > 0.7 for detecting emotional and quality-of-life decline post-surgery. Convergent validity was demonstrated through a moderate correlation between the DT and the EWB subscale scores (r
conclusionThe DT is a valid and responsive tool for detecting psychological distress in PE patients. Its high sensitivity supports its use in routine screening.
