Validation study of the Japanese version of MD Anderson Symptom Inventory for Brain Tumor module.

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
objectiveThe MD Anderson Symptom Inventory for Brain Tumor (MDASI-BT) module is a widely used instrument for measuring symptom burden and interference of daily activities in brain tumor patients. This study aims to develop and validate its Japanese version (MDASI-BT-Japanese).
methodsFollowing forward and backward translation of the original MDASI-BT into Japanese, understandability and feasibility were assessed by cognitive debriefing. Subsequently, patients with brain tumors were asked to fill out MDASI-BT-Japanese and European Quality of Life-5 Dimensions (EQ-5D). Feasibility, reliability and validity of MDASI-BT-Japanese were assessed.
resultsCognitive debriefing confirmed overall ease of completion and good understandability. The study population composed of 140 patients with brain tumors (most commonly gliomas). The mean symptom severity score and mean interference score were 1.9 ± 1.7 and 2.8 ± 2.7, respectively. The top items included distress and drowsiness for symptom severity and general activity and work for interference. The median time required was 4 minutes (range, 0.5-30), and missing values were seen in 1%. Internal consistency was proven by excellent Cronbach's coefficient alpha (0.94 for symptom severity, 0.92 for interference). Test-retest reliability was assessed with acceptable intra-class correlation coefficient (mean, 0.76). Correlation efficient ranged between 0.7 and 0.9 for convergent validity. Known-group validity was confirmed by significantly different mean symptom severity score and mean interference score among patients with different performance status. As evidence of concurrent validity, MDASI-BT-Japanese correlated with EQ-5D in the hypothesized magnitude and direction.
conclusionsThe newly developed MDASI-BT-Japanese has demonstrated feasibility, reliability and validity in evaluation of clinical benefit in Japanese-speaking brain tumor patients.
