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/

objectivesEating a variety of foods has been recommended in the dietary guidelines of many developed nations, as well as global dietary guidelines. We investigated the potential effect of dietary diversity on the risk of total mortality and major causes of mortality in a large-scale cohort study involving the Japanese population. SUBJECTS/

methodsFrom 1995 to 2012, 79,904 participants (37,240 men and 42,664 women) aged 45 to 74 years, without histories of ischemic heart disease, stroke, or cancer were followed-up for a median of 14.9 years. We used 133 food and beverage items listed on a 5-year follow-up food frequency questionnaire, and the daily frequency of consumption for each item (excluding five alcoholic beverages) was counted. Multivariable-adjusted Cox proportional hazards regression models were used to calculate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) to compare the highest and lowest quintiles.

resultsAn inverse association was identified between total dietary diversity and mortality rates in women (highest quintile HR: 0.81; 95% CI: 0.71, 0.92; p for trend = 0.002) but the same trend was not observed in men (highest quintile HR: 0.96; 95% CI: 0.87, 1.10; p for trend = 0.266). In addition, fruit diversity was associated with lower mortality rates in men (highest quintile HR: 0.87; 95% CI: 0.79, 0.95; p for trend = 0.006), whereas soy diversity was associated with lower mortality rates in women (highest quintile HR: 0.89; 95% CI: 0.79, 1.00; p for trend = 0.004). With regard to men, meat and fish diversity were associated with higher mortality rates (highest quintiles of meat and fish diversity HR: 1.15 [95% CI: 1.06, 1.25] and 1.12 [95% CI: 1.02, 1.22], respectively).

conclusionsThese findings indicate that consuming a greater diversity of total foods and increasing the diversity of fruit and soy consumed have considerable public health implications.
