Translation and Validation of the Bangla Version of the Osteoporosis Knowledge Assessment Tool (OKAT).

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
objectiveThis study aimed to translate and validate the Osteoporosis Knowledge Assessment Tool (OKAT) for Bangla-speaking populations in Bangladesh by assessing its internal consistency, test-retest reliability, content validity, and construct validity.
methodsThis methodological validation study was conducted over 22 months in the Department of Rheumatology at Bangladesh Medical University, Dhaka. The study comprised two phases. The first phase included the translation of the OKAT questionnaire into Bangla (OKAT-Bangla), and the second phase included the psychometric validation of the OKAT-Bangla. A total of 126 individuals attending the study department were purposively selected as study participants. Data collection was conducted via a case record form. Each participant was subjected to a face‒to‒face interview followed by a retest after 1 week. To validate the OKAT-Bangla, internal consistency and reliability were tested along with content and construct validation. Statistical analysis was conducted via IBM SPSS Statistics for Windows, version 23.0.
resultsIn this study, OKAT-Bangla demonstrated internal consistency with Cronbach's alpha (α) of 0.636 and test‒retest reliability with a correlation coefficient (r) ranging from 0.55 to 0.94. Content validity was tested by expert rheumatologists, with an item-level content validation index of 1 and a scale-level content validation index of 1, indicating excellent relevancy. Principal component analysis revealed nine components with eigenvalues >1. The rotation sums of the squared loading variances ranged from 6.184% to 8.060%. These findings collectively establish the OKAT-Bangla as a valid instrument for measuring osteoporosis knowledge.
conclusionThe OKAT-Bangla is a valid, reliable, and culturally appropriate instrument for assessing osteoporosis knowledge in Bangla-speaking populations.
