Synthesis in BMJ (Clinical research ed.), 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05346978 (Effect of Consumption of a Lyophilized Nasturtium), which is not on this map. Cited by 293 papers, 21 of them syntheses that pooled it.

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.

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.

Abstract

objectiveTo investigate the independent effects of intake of fruit and vegetables on incidence of type 2 diabetes.

designSystematic review and meta-analysis. DATA SOURCES: Medline, Embase, CINAHL, British Nursing Index (BNI), and the Cochrane library were searched for medical subject headings and keywords on diabetes, prediabetes, fruit, and vegetables. Expert opinions were sought and reference lists of relevant articles checked. STUDY SELECTION: Prospective cohort studies with an independent measure of intake of fruit, vegetables, or fruit and vegetables and data on incidence of type 2 diabetes.

resultsSix studies met the inclusion criteria; four of these studies also provided separate information on the consumption of green leafy vegetables. Summary estimates showed that greater intake of green leafy vegetables was associated with a 14% (hazard ratio 0.86, 95% confidence interval 0.77 to 0.97) reduction in risk of type 2 diabetes (P=0.01). The summary estimates showed no significant benefits of increasing the consumption of vegetables, fruit, or fruit and vegetables combined.

conclusionIncreasing daily intake of green leafy vegetables could significantly reduce the risk of type 2 diabetes and should be investigated further.
