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
purposeWe evaluated the psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer high-dose chemotherapy specific quality of life questionnaire module (EORTC QLQ-HDC29) when implemented with Korean patients by conducting a multicenter, longitudinal study in three Korean hospitals.
methodsA total of 226 patients who scheduled to receive the HDC followed by hematopoietic stem cell transplantation (HSCT) were enrolled. The patients were asked to complete three questionnaires [the EORTC Core Questionnaire (QLQ-C30), QLQ-HDC29, and the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation] at four points in time: before HSCT and 100, 180, and 365 days after HSCT. Standard validity and reliability analyses were performed.
resultsInternal consistency of the QLQ-HDC29 was generally acceptable, as tested by Cronbach's α, except for the scales body image and the inpatient issues. Cronbach's α values for the Korean version of the QLQ-HDC29 were almost in accordance with results of the original version, except for the scales body image (lower to the original QLQ-HDC29, α = 0.73) and impact on family (higher to the original QLQ-HDC29, α = 0.52). Known-group comparison analyses showed significantly higher symptom burdens in patients with poor performance status or graft versus host disease (similar to the original QLQ-HDC29). The QLQ-HDC29 indicated good convergent and discriminant validity and showed responsiveness to changes in line with a clinical course over time after HSCT.
conclusionsThe QLQ-HDC29 is generally reliable and adequate to assess QoL in Korean patients undergoing HDC followed by HSCT.
