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 purposeRecent studies reported the differential effect of docosahexaenoic (DHA) and eicosapentaenoic acids (EPA). We examined the differential association of DHA and EPA with carotid intima-media thickness (IMT) in Japanese individuals in Japan and in U.S. white individuals and explored whether DHA or EPA contributes to the difference in IMT between the two groups.

methodsA population-based cross-sectional study in 608 Japanese and U.S. white men aged 40 to 49 was conducted to assess IMT, serum DHA, EPA, and other cardiovascular risk factors.

resultsJapanese compared to U.S. whites had significantly lower IMT (mean±SD, 618±81 and 672±94 μm for Japanese and whites, respectively; P<0.001) and had >2-fold higher levels of DHA and EPA. DHA, but not EPA, had an inverse association with IMT in both Japanese and U.S. whites. The inverse association remained only in Japanese men after adjusting for risk and other factors. The significant difference in multivariable-adjusted IMT became nonsignificant after further adjusting for DHA (mean difference, 17 μm; 95% CI, -8 to 43; P=0.177) but not EPA. In this multivariable-adjusted model, DHA but not EPA was a significant predictor of IMT (P=-0.032 versus 0.863, respectively).

conclusionsThese data suggest that DHA may have a more potent antiatherogenic effect than EPA, especially in levels observed in the Japanese, independent of risk factors.
