Health Literacy, Numeracy, and Health Promotion: A Secondary Analysis of the Choosewell 365 Workplace Trial.
Trial report in American journal of preventive medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
introductionHealth literacy and numeracy are linked to obesity and dietary behaviors. This study investigates whether the effect of a workplace behavioral intervention to prevent weight gain and improve diet differed by employee health literacy and numeracy.
methodsChooseWell 365 was an RCT of hospital employees testing a 12-month intervention using nudges and feedback to promote healthier choices, building on existing cafeteria traffic light labels (e.g., green=healthy, red=unhealthy). Health literacy and numeracy were measured with the Newest Vital Sign (range=0-6) and General Numeracy Scale (range=0-3). Mixed-effects linear models examined if intervention effects on cafeteria purchases, diet quality (Healthy Eating Index 2015, range=0-100), and weight change over 24 months differed by higher versus lower health literacy or numeracy. Data were collected in 2016-2020 and analyzed in 2020-2021.
resultsIn 12 months, 510 participants completed the Newest Vital Sign and General Numerancy Scale; 36.7% had Newest Vital Sign<6 (lower health literacy) and 31.6% had General Numerancy Scale<2 (lower numeracy). Intervention participants increased healthy purchases over 24 months compared with controls in both higher and lower health literacy and numeracy groups. At 12 months, Healthy Eating Index 2015 scores increased in intervention versus control participants with lower health literacy (5.5 points, 95% CI=1.51, 9.54) but not in those with higher health literacy (p-interaction=0.040). BMI did not differ by health literacy or numeracy.
conclusionsA behavioral intervention improved cafeteria food choices of hospital employees of varying health literacy and numeracy levels and improved diet quality among employees with lower health literacy, suggesting this group also improved food choices outside of work.
