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

This research sought to evaluate the food safety knowledge of street food vendors and the sanitary compliance status of their vending facilities, Zululand District, South Africa. Data collection was done in a face to face interview with respondents in a cross-sectional survey research design. Data was collected from 399 randomly selected street food vendors and 200 randomly selected street food vending facilities. Only a minority of the street food vendors had attended high school (47 %) and the vast majority (77 %) of them had not attended any food safety training courses. Overall, the vast majority (76 %) of the street food vendors had low food safety knowledge and only 14 % of the street food vending sites had high compliance with sanitary conditions. In conclusion, this study demonstrates that most of vending facilities of street food vendors constitute a food safety risk to the consumers. This was primarily due to the possession of inadequate food safety knowledge of street food vendors, non-compliant street food vending infrastructure, and inadequate monitoring and controls by competent authorities. It is recommended that, authorities should implement the food stalls/caravan system in areas with adequate sanitation and use the licensing and permit tool to ensure control and adherence to food safety regulations and street food vendors and health inspectors should be trained on safe food handling principles and practice.
