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.
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
Background: Food composition-linked grocery sales data provide time- and resource-efficient, low-bias population nutrition insights. This is particularly valuable in the Inuit-majority territory of Nunavut, Canada, where up-to-date diet-related data are lacking amid a nutrition transition. Objectives: We aimed to investigate whether, in 21 Nunavut communities served by a market-dominant retailer: Methods: Each of 24,463 unique products sold between 1 February, 2013, and 31 July, 2019 was matched to its closest nutritional equivalent in the Canadian Nutrient File or the United States FoodData Central database for energy, macronutrient, and fiber values to be multiplied by product amount. Per capita standardization was performed with 2016 Census data. Analysis of variance tested for the statistical significance of differences in means. Results: Consumer nutrition patterns were seasonally consistent. In the 4 community size levels other than Iqaluit, percentage of energy from protein was relatively low (9%-10%), percentage of energy from carbohydrate was high (63%-66%), and food energy density was high (295-319 kcal/100 edible g). Purchases were least energy-dense in Iqaluit and the largest community size quartile (276 and 295 kcal/100 edible g, respectively). Among 16 categories and across community size levels, Beverages and Juices & Drinks constituted roughly one-fifth of energy and one-third of carbohydrates sold. Sale of fiber was consistently low (6-7 g/capita/day). Conclusions: To our knowledge, this is the first analysis of nutrient-linked grocery sales data in the Arctic. Our findings reveal energy-dense, high-carbohydrate, low-protein, low-fiber store-bought grocery sales in the context of an advanced nutrition transition in Nunavut.
