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

backgroundThere has been emerging attention to investigate the possible role of some dietary factors in the pathogenesis of Parkinson's disease (PD); however, evidence about the relationship between dietary components and the risk of PD is limited. The aim of this study was to determine the association between major dietary patterns and the risk of PD.

methodsThis case-control study was performed on 105 patients with newly diagnosed PD and 215 healthy controls. Diagnosis of Parkinson's disease was made based on the UK Brain Bank criteria. Usual dietary intakes were collected by a validated semi-quantitative food frequency questionnaire. Dietary patterns were detected by principal component analysis.

resultsFour dietary patterns, including traditional, healthy, western, and light dietary patterns, were identified. After considering all potential confounders, individuals with the highest tertile of traditional dietary pattern scores had a lower risk of PD than those with the lowest tertile (OR: 0.002; 95% CI: 0.000-0.016). A similar inverse association between the healthy pattern (OR: 0.314; 95% CI: 0.131-0.750) and light pattern (OR: 0.282; 95% CI: 0.121-0.654) and risk of PD was revealed. In contrast, adherence to the western dietary pattern was associated with PD incidence (OR: 7.26; 95% CI: 2.76-19.09).

conclusionsThe findings of this study suggest that adherence to western dietary pattern could increase the risk of PD by approximately seven times. However, the traditional, healthy, and light dietary patterns had an inverse relationship with PD risk.
