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

objectiveTo study the extent and nature of free-to-air television advertisements for non-core products (e.g., fast food or soda) directed at children in Hong Kong.

designTelevision programs from two major Hong Kong free-to-air television channels airing between 06.00 and 24.00 hours from October 2018 to January 2019 were recorded. Eight nonconsecutive days (four weekdays and four weekend days) were selected for analysis. Pearson's χ2 tests were conducted to compare the pattern of food advertisements by program categories, days of the week, television viewing periods and persuasive marketing techniques.

settingFree-to-air television programs.

participantsNot applicable.

resultsOf the 10 348 commercials identified, 18·4 % were for foods, and 35·2 % of these were for non-core items. Baby and toddler milk formula (19·5 %) were the most advertised food products, while the most frequently advertised non-core food was fast foods (12·3 %). There was a higher non-core to core product ratio during prime time than the children's time slot (7 v. 1·7). Non-sports celebrity endorsement (27·1 %) was the most frequently used persuasive marketing technique overall, while that for non-core products was sensory characteristics (38·2 %). Most food product placements recorded were non-core products, mentions of local and fast food restaurants and recipe additions.

conclusionsNon-core products were highly advertised in Hong Kong, while core product advertising was infrequent. Regulations on junk food advertising in Hong Kong should focus on prime time, as well as on food product placement, to reduce children's exposure to persuasive junk food marketing.
