Initial development of a patient-reported outcome measure of disability due to Katakori via evaluating patient comprehensibility and comprehensiveness.
Article in Journal of physical therapy science, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
[Purpose] "Katakori" refers to a nonspecific symptom, including discomfort or dull pain, that is experienced around the occiput and that extends through the cervical spine to the acromion and scapular area. This study aimed to develop a patient-reported outcome measure of disability due to Katakori, namely the Katakori Disability Index, via evaluating patient comprehensibility and comprehensiveness. [Participants and Methods] We conducted a semi-structured interview among participants who had experienced Katakori consistently during the past month to examine patient comprehensibility and comprehensiveness; we particularly used the thinking-aloud method and cognitive debriefing to evaluate comprehensibility. [Results] We initially tested a provisional version of the Katakori Disability Index with 24 items using two 11-point numeric rating scales in a subset of 10 participants. Considering the issues identified concerning comprehensibility and comprehensiveness, we created a second draft of the Katakori Disability Index with two 6-point Likert scales, modified items, and four additional items. The second draft was tested in another subset of 10 participants. We eventually developed a 31-item Katakori Disability Index with modified instructions and items, two additional items, and a post-survey checklist; all these features addressed the concerns identified and suggestions obtained in the second round of interviews. [Conclusion] We developed a 31-item Katakori Disability Index with content validity.
