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

backgroundTo reduce diet-related chronic disease, policymakers have proposed requiring health warnings on sugar-sweetened beverages (SSBs). Health warnings reduced purchases of these products by 22% in our recent randomized controlled trial, but the mechanisms remain unclear. PURPOSE: We sought to identify the psychological mechanisms that explain why SSB health warnings affect purchase behavior.

methodsIn 2018, we recruited 400 adult SSB consumers to complete a shopping task in a naturalistic convenience store laboratory in North Carolina, USA. We randomly assigned participants to either a health warning arm (all SSBs in the store displayed a text health warning) or to a control arm (SSBs displayed a control label). Participants selected items to purchase with cash.

resultsCompared to control labels, health warnings elicited more attention, negative affect, anticipated social interactions, and thinking about harms (range of ds = 0.63-1.34; all p < .001). Health warnings also led to higher injunctive norms about limiting SSB consumption (d = 0.27, p = .008). Except for attention, all of these constructs mediated the effect of health warnings on SSB purchases (all p < .05). In contrast, health warnings did not influence other attitudes or beliefs about SSBs or SSB consumption (e.g., healthfulness, outcome expectations, and response efficacy).

conclusionsHealth warnings on sugar-sweetened beverages affected purchase behavior by eliciting negative emotions, increasing anticipated social interactions, keeping SSBs' harms at top of mind, and shifting norms about beverage consumption. Results are consistent with recent studies of why tobacco warnings influence quitting behavior, pointing toward a general framework for understanding how health warnings affect behavior.
