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

objectiveThe primary objectives of the study were to examine: 1) how increased availability of healthier items at a zoo concession stand affects sales and 2) how animal character marketing on zoo menu boards affects sales revenue.

methodsAn intervention was conducted over an 8-week period. On alternating weeks, zoo animal characters were systematically paired with and removed from healthy food items on a zoo concession menu board. Sales and revenue data were analyzed using frequencies, a Poisson regression model, and a negative binomial regression model, respectively.

resultsNewly introduced healthy items represented 8.2% of sales and 4.9% of revenue. Healthy item unit sales were significantly higher (P = .006) during the weeks animal cartoon characters were displayed, although there was no impact on revenue. CONCLUSIONS AND IMPLICATIONS: Findings suggest nonbranded character marketing is a viable strategy for promoting healthy products in family-friendly venues where concessions are sold.
