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

BACKGROUND AND

aimsThe Nordic diet (ND), is supposed to be associated with a reduced cardiovascular risk; however, clinical trials have led to inconsistent results regarding the effect of this diet on cardio-metabolic markers. Using systematic review and meta-analysis of randomized controlled trials (RCTs), this study aimed to investigate the effect of the ND on circulating levels of total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol, and triglyceride (TG), as well as blood pressure in human adults.

methodsPubMed, Scopus, ISI Web of Science, and Google Scholar were searched up to February 2018 for relevant articles. Random effects model was used to estimate the overall effects.

resultsFive RCTs consisting of 513 participants were included in the present review. The meta-analysis of five eligible studies showed that ND significantly reduces the total [weighted mean difference (WMD) = - 0.38 mmol/l, 95% confidence interval (CI) - 0.76, - 0.01, P = 0.044] and LDL cholesterol (WMD = - 0.30 mmol/l, 95% CI - 0.54, - 0.06, P = 0.013) levels compared with the control groups; however, none was seen for HDL cholesterol and TG levels. The meta-analysis of four eligible RCTs revealed that the ND significantly reduces the systolic (WMD = - 3.97 mmHg, 95% CI - 6.40, - 1.54, P = 0.001) and diastolic blood pressure (WMD = - 2.08 mmHg, 95% CI - 3.43, - 0.72, P = 0.003).

conclusionThe Nordic dietary pattern improves blood pressure and also some of blood lipid markers and it should be considered as a healthy dietary pattern.
