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

During COVID-19, Chelsea, a city in Massachusetts, USA, implemented an unconditional cash transfer (UCT) programme ('Chelsea Eats') that provided a nine-month benefit of up to US$400 per month to low-income households, allocated via lottery. UCTs are increasingly common, but their dietary impacts in high-income countries are unclear. In a randomized experiment, 905 individuals assigned to receive UCTs and 555 controls completed a 24-h diet recall after 4-6 months. At baseline, 90% identified as Latino/a, and 86% experienced food insecurity. At follow-up, average caloric intake was 1,351 kcal among those in control-far less than the approximately 2,060 kcal recommended by the Dietary Guidelines for Americans. The intervention led to increased kilocalories (+146 kcal), and increased fruit (+0.17 cup equiv.), vegetable (+0.14 cup equiv.) and unprocessed meat (+0.54 oz.) consumption. These findings suggest that a recurring UCT reduced caloric deficits and improved intake of nutrient-dense foods among this food-insecure population in the United States.
