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

objectiveTo assess the use of cod-liver oil supplements among Norwegian women and to examine dietary, lifestyle, demographic, and health factors associated with use of this supplement.

designCross-sectional study. SETTING AND SUBJECTS: The study is based on data from a food frequency questionnaire from 1998 answered by 37,226 women aged 41-55 y, who in 1991/1992 participated in the Norwegian component of the European Prospective Investigation into Cancer and Nutrition (EPIC). The Norwegian EPIC cohort was based on a random nation-wide sample of Norwegian women.

resultsCod-liver oil supplement use was reported by 44.7% of the participating women. Subjects with higher education, high physical activity level, and body mass index (BMI) in the normal range were more likely to use cod-liver oil supplements. Consumption did also increase with increased age as well as with increased reported consumption of fruits, vegetables, fatty fish, lean fish, and vitamin D (excluding the vitamin D contribution from cod-liver oil). Energy intake was higher among cod-liver oil users than nonusers. Whole-year daily users of cod-liver oil were also more likely to take other dietary supplements (OR=2.45, 95% CI: 2.28-2.62). Never smokers were more likely to use cod-liver oil supplements than current smokers.

conclusionUse of cod-liver oil is associated with several sociodemographic factors, self-reported health issues, and intake of fish, fruit, and vegetables. When assessing the relationship between cod-liver oil use and occurrence of chronic diseases potential confounders need to be considered. Cod-liver oil use seemed not to be matched with vitamin D needs. Thus, emphasis on assessing vitamin D status by measuring levels in blood should be investigated further, in particular, among people living in northern latitudes.
