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.

Abstract

backgroundTo help address rising rates of obesity in children, evidence is needed concerning impacts of common forms of marketing for unhealthy child-oriented food products and the efficacy of educational interventions in counteracting any detrimental impacts of such marketing. This study aims to explore parents' responses to advertising for unhealthy children's food products that employ different types of persuasive appeals and test whether a counter-advertising intervention exposing industry motives and marketing strategies can bolster parents' resistance to influence by unhealthy product advertising.

methodsN = 1613 Australian parents were randomly assigned to view online either a: (A) non-food ad (control); (B) conventional confectionery ad (highlighting sensory benefits of the product); (C) pseudo-healthy confectionery ad (promoting sensory benefits and health attributes of the product); (D) conventional confectionery ad + counter-ad (employing inoculation-style messaging and narrative communication elements); (E) pseudo-healthy confectionery ad + counter-ad. Parents then viewed various snacks, including those promoted in the food ads and counter-ad. Parents nominated their preferred product, then rated the products.

resultsExposure to the conventional confectionery ad increased parents' preference for the advertised product, enhanced perceptions of the product's healthiness and reduced sugar content and boosted brand attitude. Exposure to the pseudo-healthy confectionery ad increased parents' preference for the advertised product, and enhanced perceptions of healthiness, fibre content and lower sugar content. The counter-ad diminished, but did not eliminate, product ad effects on parents' purchasing preference, product perceptions and brand attitudes. The counter-ad also prompted parents to perceive processed foods as less healthy, higher in sugar and lower in fibre and may have increased support for advertising regulation.

conclusionsExposure to unhealthy product advertising promoted favourable perceptions of products and increased preferences for advertised products among parents. Counter-advertising interventions may bolster parents' resistance to persuasion by unhealthy product advertising and empower parents to more accurately evaluate advertised food products.
