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
backgroundThe retail environment is an important determinant of food package redemption in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).
objectiveThe objectives of this study were to describe where Massachusetts WIC households redeemed their food benefits each month and monthly variations in benefit redemption depending on a household's most frequently used vendor type each month.
designThese were cross-sectional and longitudinal analyses of administrative data provided by Massachusetts WIC. PARTICIPANTS/
settingMonthly redemption data for 209,973 households shopping at approximately 1,000 unique vendors between January 2015 and August 2019 were analyzed.
main outcome measuresOutcomes were mean monthly percentage of households that relied on each vendor type when redeeming benefits and mean monthly percent redemption for each benefit category. STATISTICAL ANALYSES PERFORMED: For each month, households were classified as using 1 of 8 vendor types. The monthly percentage of households redeeming at each vendor type was calculated, as well as the monthly percent redemption for each benefit category by vendor type. The averages of these monthly percentages were computed for 2015 and 2019. Data from months when households did not redeem any benefits were excluded from primary analyses because it was not possible to determine their vendor type for that month.
resultsOn average across months in 2019, the majority of Massachusetts WIC households (63%) relied on large vendors only (ie, superstores, supermarkets, and large grocery stores) when redeeming benefits, and 5% relied on small grocery or convenience stores only. Between 2015 and 2019, mean monthly reliance on small grocery and convenience stores decreased by 3.1 and 0.7 percentage points, respectively. Compared with other vendor types, households that redeemed benefits at superstores only had, in an average month, lower redemption levels for most benefit categories. For example, in the 2019 mean across months, percent redemption of breakfast cereal was 53% among households redeeming at superstores only compared with 74% for those redeeming at small grocery stores only. By contrast, households that relied on small grocery stores only had, in an average month, lower redemption levels for yogurt and cash value benefit compared with other vendor types; for example, in the 2019 mean across months, percent redemption of yogurt was 34% among households redeeming at small grocery stores only compared with 62% among those redeeming at supermarkets only.
conclusionsResults suggest that retail-based efforts to increase redemption should consider vendor-type reliance. Strategies to increase redemption may be especially important for WIC shoppers relying on superstores.
