1 · What the graph read from it

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.

2 · The registry

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

objectiveThe present work aimed at cross-cultural adaptation and validation of the health literacy assessment tool Newest Vital Sign (NVS) in general population (GP) and highly educated (HE) samples of Brazilian adults.

designAn expert committee reviewed the translation and back-translation processes and the cultural adaptation. The construct validity was analysed with confirmatory factor analysis and via associations with features of the study population.

settingThe final validation test was performed in two different populations from Londrina, a large town in southern Brazil. SUBJECTS: Brazilian adults: GP (adult clients of community pharmacies; n 189) and HE (public school teachers; n 301).

resultsThe tool under validation showed good cross-cultural adaptation and internal consistency, with Cronbach's α of 0·75 for GP and 0·74 for HE. Confirmatory factor analysis showed acceptable models and identified two independent factors according to the relationship between components and numeracy for both GP and HE data. According to the Brazilian Portuguese version of the NVS instrument (NVS-BR), 48·7 % of GP and 33·5 % of HE presented adequate health literacy; this condition was inversely associated with age for both populations and directly correlated with educational level for GP.

conclusionsThe NVS-BR showed good validity in two different populations of Brazilian adults and can be considered an alternative in screening for inadequate health literacy.
