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

Adhering to a gluten-free diet (GFD) is essential for individuals with gluten-related disorders such as coeliac disease, dermatitis herpetiformis, gluten ataxia, and wheat allergy. Approximately 1%-2% of the population is affected by these conditions. Access to affordable, high-quality gluten-free products (GFPs) is crucial for maintaining dietary compliance and well-being. This study explores the experiences of those on a GFD, focusing on the availability, quality, and cost of GFPs compared to non-GFPs. The study was conducted in two stages: (1) An online survey was distributed to Australian Coeliac Association and Coeliac New Zealand members to gather data on shopping habits, preferred GFPs, and opinions on product availability, value, and quality. (2) Retail observations involved creating a `shopping basket/list' based on survey results to compare the availability and price of GFPs versus non-GFPs in major supermarkets across urban and rural areas. Results from 1501 Australian and 700 New Zealand respondents and retail observations revealed that GFPs are significantly more expensive and of lower quality than non-GFPs. Commonly purchased items include bread, pasta, crackers, flour, and breakfast cereals. The study highlights the need for improved availability, affordability, and quality of GFPs, especially in bridging the cost disparity between urban and rural areas.
