Validation of oral health literacy instrument in Nepali language: a tool to assess oral health literacy of Nepalese population.
Article in BMC oral health, 2026. 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
backgroundOral health literacy is the capacity of processing and understanding basic oral health information. Instruments are available for its measurement in English and other languages. But no validated tool is available in Nepali language that could be used to assess oral health literacy level of Nepalese population. The objective of this study was to translate and validate the Nepalese version of Oral Health Literacy Instrument (OHLI-N) from the original English version.
methodsThe English version of OHLI along with oral health knowledge test was translated into Nepali language. The translated version was reviewed and pretested on conveniently selected 30 participants. A cross-sectional study was conducted among conveniently selected 160 adult patients of 18 years and above visiting dental OPD of a tertiary care center for testing validity and reliability of OHLI-N. Oral examination was done to record DMFT and CPI scores. Concurrent validity, construct validity and predictive validity of OHLI-N was determined. Internal consistency of OHLI-N was evaluated using Cronbach's alpha (α). OHLI-N was readministered in 25 patients after 2 weeks to assess test-retest reliability using intra-class correlation coefficient (ICC).
resultsThe mean overall OHLI-N score of the participants was 65.9 ± 17.6. OHLI-N scores were significantly associated with educational level of participants (p < 0.001). A significant positive correlation (r
conclusionThe OHLI-N showed good validity and reliability for assessing the oral health literacy level of adult patients visiting a tertiary care center of Nepal.
