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 increasing availability of unhealthy processed food products is linked to rising rates of non-communicable diseases and obesity in low- and middle-income countries. Voluntary actions (VAs) are often adopted in lieu of regulating the composition, production, marketing and sale of unhealthy commodities, but their effectiveness is unclear. This realist review examines VAs adopted by the food and beverage industry in low- and middle-income countries. We developed a conceptual framework and followed a three-stage search to identify literature and VAs and, adhering to the Realist and Meta-narrative Evidence Syntheses: Evolving Standards (RAMESES) guidelines, we produced a synthesized analysis of VAs. VAs, often initiated in response to governments' efforts to introduce regulations, were difficult to evaluate due to vague language and a lack of enforcement mechanisms. The review found no evidence indicating that VAs are effective in safeguarding public health. Yet their implementation has resulted in weaker responses and policy substitution, and so we suggest that VAs have the potential to negatively influence public health and policy. The United Nations should rescind their endorsement of industry involvement and mandatory measures should be favoured over VAs.
