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

aimsRed blood cell membrane fatty acids can be used alongside self-reported dietary assessment methods, such as food frequency questionnaires, to measure the validity of self-reported intakes. This study aimed to validate fatty acid intakes estimated from the Australian Eating Survey food frequency questionnaire against red blood cell profiles of healthy Australian adults.

methodsDemographic data and dietary intakes of fatty acids were collected, and red blood cell membrane fatty acid composition was measured using gas chromatography. Bland-Altman plots and concordance correlation coefficients (ρ

resultsA total of 58 participants (67% female, mean age 39.6 years) yielded 105 observations. Total saturated, total monounsaturated, total polyunsaturated fats including Eicosapentaenoic acid, Docosahexaenoic acid, Docosapentaenoic acid, and linoleic acid were within limits of agreement with moderate associations (ρ

conclusionSelf-reported intakes from the Australian Eating Survey food frequency questionnaire were in moderate agreement (ρ
