Korean Version of the Patient Perception of Study Medication Questionnaire: Translation and Linguistic Validation.
Article in International neurourology journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThe patient perception of study medication (PPSM) questionnaire consists of 12 questions designed to quantify patient satisfaction with the efficacy of study treatment by focusing on specific changes that patients experience during the study period. This study aimed to develop a Korean version of the PPSM questionnaire.
methodsThe linguistic validation process consisted of obtaining permission for translation, forward translation, reconciliation, backward translation, cognitive debriefing, and proofreading. Two independent bilingual translators translated the original version of the questionnaire, and a panel discussed and combined the 2 versions. Another independent translator performed backward translation of the reconciled version, after which 15 patients underwent the cognitive debriefing.
resultsThe 12 questions and 4 response scales of the PPSM questionnaire were forward translated into 2 Korean versions. The terms were adjusted to conceptually equivalent expressions in Korean. After backward translation, the panel made minor changes to the forward translations for brevity and better readability. No difficulties were experienced during cognitive debriefing by 15 patients, and all items were reported to be generally easy to understand.
conclusionThe Korean version of the PPSM questionnaire has been successfully translated and validated. The questionnaire is appropriate for assessing symptom satisfaction in patients that undergo benign prostatic hyperplasia pharmacotherapy.
