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

backgroundLow circulating levels of coenzyme Q(10) (CoQ(10)) have been associated with increased cancer incidence and poor prognosis for a number of cancer types, while a recent prospective study observed a positive association for CoQ(10) with breast cancer risk.

methodsWe prospectively examined the association of plasma CoQ(10) with breast cancer risk in a nested case-control study of Chinese women within the Shanghai Women's Health Study (SWHS). Prediagnostic plasma samples were obtained from 340 cases and 653 age-matched controls and analyzed for total CoQ(10).

resultsA borderline significant inverse association for breast cancer incidence with plasma CoQ(10) level was observed by a conditional logistic regression model adjusted for age and age at first live birth, which became significant after elimination of cases diagnosed within 1 year of blood draw (P(trend) = 0.03). This association was independent of menopausal status. Plasma CoQ(10) levels were also observed to be significantly associated with circulating γ-tocopherol (r = 0.50; P < 0.0001) and α-tocopherol (r = 0.38; P < 0.0001) levels.

conclusionsCirculating levels of CoQ(10) were generally low in this population and the observed association with breast cancer risk may be limited to those women with exceptionally low values. IMPACT: This study reports an inverse relationship between circulating CoQ(10) and breast cancer risk, while the only other prospective study of CoQ(10) and breast cancer to date found a positive association. Lower levels of CoQ(10) in the SWHS population suggest that the 2 studies may not be contradictory and indicate a possible nonlinear (U-shaped) association of CoQ(10) with risk.
