Development and validation of the Japanese version of the Death Literacy Index (DLI-J) and its short form (DLI-J-9).

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
Aim: To translate, culturally adapt, and psychometrically validate the Japanese version of the Death Literacy Index (DLI-J) and its short-form version (DLI-J-9) to assess death literacy among Japanese adults. Methods: A multiphase mixed-methods design was employed. The process included forward translation, reconciled single translation, back translation, translation review, cognitive interviews ( Results: The DLI-J demonstrated excellent psychometric properties. CFA supported the six-factor structure of the DLI-J (Tucker-Lewis index [TLI] = 0.940, comparative fit index [CFI] = 0.947, standardized root mean square residual [SRMR] = 0.048, and root mean square error of approximation [RMSEA] = 0.063) and the two-factor structure of the DLI-J-9 (TLI = 0.945, CFI = 0.960, SRMR = 0.042, and RMSEA = 0.069). Internal consistency was excellent for the total DLI-J scale ( Conclusion: The DLI-J and DLI-J-9 are psychometrically robust instruments for assessing death literacy.
