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

purposeConsuming 30 g of nuts/day is recommended to reduce chronic disease. However, nut consumption appears far from ideal among several populations. A potential strategy to increase consumption is to add nuts to a staple, for example, bread. Whether the health benefits and acceptability of nuts persist in this form is currently unknown. Thus, we examined the effects of consuming three nut-enriched breads on postprandial glycaemia, satiety, gastrointestinal tolerance, dietary intakes, and acceptance.

methodsIn this controlled, crossover study, 32 participants were randomly allocated to receive one of four breads for 8 days each. Three breads contained either 30 g of finely sliced hazelnuts, 30 g semi-defatted hazelnut flour, or 15 g of each (amounts per 120 g bread) and were compared with a control nut-free bread. Blood glucose response was measured over 120 min, along with ratings of gastrointestinal discomfort. Appetite ratings and diet diaries were completed during each treatment period.

resultsArea under the blood glucose curve was significantly lower for the nut breads compared to the control bread (all P < 0.001), with no significant differences between the nut breads (all P ≥ 0.130). There were no significant differences in satiety (all P ≥ 0.135) or gastrointestinal symptoms (all P ≥ 0.102) between the breads. Acceptance was highest for the finely sliced hazelnut bread. Furthermore, consuming hazelnut-enriched bread improved diet quality, increasing monounsaturated fat, vitamin E, and dietary fibre intakes.

conclusionBread appears to be an effective and acceptable vehicle for increasing nut consumption, resulting in improved postprandial glycaemia and diet profiles. Long-term studies are now required.
