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

objectiveNewfoundland and Labrador (NL) introduced Canada's first excise tax on sugar-sweetened beverages (SSB) in 2022. Industry marketing practices in response to SSB taxation may affect public health impacts. We examined changes in posted beverage pricing and marketing of taxable and non-taxable beverages in NL before and after the SSB tax was implemented.

designPre-/post-observational study with in-store audits of beverage prices and marketing. Changes including pricing discounts and promotions were assessed at the individual beverage level for pre/post-tax implementation years.

settingEighty food stores (grocery, convenience, drug and dollar) in NL, Canada.

resultsThere was no evidence of a change in posted shelf prices between pre/post years. There was a significant increase (+2·5 %,

conclusionsThe lack of change in posted prices of taxable SSB indicates that the NL SSB tax was not communicated at the point of decision-making. While some marketing changes post-tax were observed, results should be interpreted cautiously as they cannot be attributed definitively to the tax. Existing literature implies that industry may adapt marketing conduct to counteract beverage taxes. Such changes were limited in NL, suggesting retailers may have opted not to display the tax rather than attempt to actively counteract it. Lack of transparency surrounding the tax may neutralise intended behavioural effects.
