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

The study aimed to develop and validate a food literacy tool for Tanzanian adults. The Tanzanian nutrition, food and health promotion experts evaluated the initial twenty-three-question food literacy tool for its relevance to the context, where its content validity was determined. The construct validity involved the analysis of food literacy information collected in a cross-sectional study involving 709 adults (484 females and 225 males) sampled from rural and urban Tanzania. Exploratory factor analysis was conducted to explore the underlying factor structure and identify the number of latent constructs. A confirmatory factor analysis using structural equation modelling verified the measurement model and confirmed the theoretical model's validity and reliability. The descriptive statistics summarised the essential characteristics of the study sample. The final tool remained with fourteen questions after removing questions with low factor loadings < 0·5 and higher uniqueness above 0·60. The model achieved construct validity through convergent and discriminant validity and construct reliability through the composite reliability exceeding 0·60 and a Cronbach's
