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

aimsMany guidelines recommend increases in potassium intake. However, the relationship of dietary potassium intake with incident cardiovascular disease (CVD) has not been examined in those with type 2 diabetes (T2DM), including sodium acting antagonistically with potassium. We investigated these relationships in Japanese patients with T2DM. MATERIALS AND

methodsThe investigation was part of the JDCP study, a nationwide prospective study begun in 2007. Analysed were 1477 persons with T2DM, 40-75 years of age, who completed a brief-type, self-administered Diet History Questionnaire at baseline. Primary outcome was a CVD event during the follow-up median 7 years (3.9-8.1 years). Hazard ratios (HRs) for CVD were estimated by Cox regression adjusted for confounders of daily potassium intake categorized by tertiles. Tertiles of sodium intake were also analysed.

resultsMean daily potassium intake in tertiles was 1877, 2627 and 3532 mg, respectively, and significant associations were not shown between potassium intake and incidence of CVD. When HRs for CVD were stratified for potassium intake in tertiles (reference group, bottom tertile) and sodium intake (reference group, bottom tertile), potassium intake in the bottom tertile and sodium intake in the second and top tertiles were associated with significantly elevated HR for CVD (2.79 [1.02-7.63] and 3.92 [1.30-11.79], respectively).

conclusionsLow potassium intake in conjunction with high sodium intake was significantly associated with increased incident CVD in persons with T2DM. However, CVD incidence was not related to high potassium intake, regardless of sodium intake.
