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

objectiveIn response to increasing hypertension rates, South Africa implemented a regulation which set a maximum total Na content for certain packaged food categories. We assess changes in reported Na intake among 18-39 years old adults living in one township in the Western Cape as a result of the implementation of the regulation in 2016.

designBy linking one set of 24-h dietary recall data to two versions of the South Africa Food Composition Database which reflect the pre-regulation and post-regulation periods, we calculated changes in Na intake due to reformulation of food products, not behaviour change. We statistically tested differences in mean consumption in this sample with paired

settingLanga, Western Cape, South Africa.

participantsSurveyed participants were residents of Langa between 18 and 39 years old (

resultsBefore and after the implementation of the regulation, there was a statistically significant decrease in the estimated Na intake among adults of 189·4 mg (137·5, 241·4;

conclusionsOur conclusions show that independent of any behavioural changes on the part of consumers, it is possible to lower Na intake by using regulations to induce food manufacturers to lower the Na levels in their products. As countries explore similar regulatory strategies, this work can add to that body of evidence to inform policies to improve the food system.
