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

introductionNo Money No Time is a culinary nutrition website focused on diet quality improvement. The aim was to compare participant retention in a 6-week eHealth challenge, with and without use of financial incentives and to compare demographic characteristic, diet quality and engagement outcomes between them.

methodsThe single-arm, pre-post studies [Spring Eatz (30 August to 17 September, 2023) and RE$ET (20th February to March, 2024)] recruited adults ≥ 18 years from Australia into a 6-week nutrition challenge delivered via weekly emails that directed participants to the No Money No Time (NMNT) purpose-built culinary and nutrition-related health website from after completing the embedded Healthy Eating Quiz (HEQ) and consenting to data use for research purposes. At the start of each challenge week participants received an email with links to targeted NMNT content, relevant recipes, plus specific time and cost-efficient advice to help improve dietary patterns. Weeks 2-5 included a prize draw of 4 × AUD$25 eGift cards randomly drawn from participants actively engaging with challenge materials and a week 6 final draw of 4 × AUD$100 eGift cards from participants completing the HEQ and feedback survey post-challenge. Data was collected on diet quality (HEQ score), demographics (gender, age, vegetarian status, number of people/weekly household grocery expenditure, expenditure on food purchased away from the home, weight and height). NMNT website analytics were collected via Active Campaign software.

resultsThe incentivised challenge recruited significantly more males (22% vs. 15%) and a younger demographic (mean age 45 y vs. 50 y) compared to unincentivized (p < 0.01). There was a significantly greater 6-week retention in the incentivised challenge compared to no incentivisation (21% vs. 16%, z-score = 2.14, p < 0.05), with significant increases in diet quality (HEQ score) in adjusted models ( + 4.5 points, p < 0.05), which was not significantly different to the unincentivized challenge p = 0.09.

conclusionsThe 6-week eHealth nutrition challenge using financial incentives improved diet quality and led to significantly greater retention compared to an unincentivized challenge, with overall retention still relatively low. Engagement with weekly emails exceeds global email marketing campaigns. Future iterations should incorporate strategies to increase participant engagement. An email campaign represents a low-cost approach to achieve short-term improvement in diet quality.
