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

objectivesTo identify high-density lipoprotein (HDL) subfractions associated with longevity in men.

designFifty-three-year prospective follow-up of Gofman's Livermore Cohort between 1954 and 2008.

settingLawrence Livermore National Laboratory.

participantsOne thousand one hundred forty-four men who consented to the study, had analytic ultracentrifuge measurements of lipoprotein subfractions at baseline, and were old enough at baseline to have survived to age 85 during follow-up. MEASUREMENTS: Survival was determined according to participant contact, Social Security Death Index, and National Death Index.

resultsThree hundred ninety men survived to 85 years old (34.1%). Survivors were less likely than nonsurvivors to be in the lowest HDL3 (% (standard error) 18.5% (2.0%) vs 27.3% (1.6%), P < .001) and HDL2 (22.1% (2.1%) vs 27.7% (1.6%), P = .04) quartiles. Logistic regression analyses showed that the lowest HDL3 quartile significantly predicted shorter longevity (P = .002), whereas the linear increases per mg/dL of HDL3 did not (P = .38), suggesting a risk threshold proximal to the 25th percentile. Men who were above the 25th HDL3 percentile had 70% greater odds of surviving until age 85 than those below this level, which persisted when adjusted for HDL2, very low-density lipoprotein (LDL), and standard risk factors. Proportional hazard analyses of survival before age 85 showed that being in the lowest HDL3 quartile increased age-adjusted cancer risk by 39% (P = .05) and noncancer risk by 23% (P = .04) when adjusted for other risk factors. Survivors also smoked less (mean ± SD 0.31 ± 0.48 vs 0.57 ± 0.56 packs/d, P < .001), had lower systolic (118.36 ± 11.08 vs 122.81 ± 13.55 mmHg, P < .001) and diastolic (70.61 ± 8.59 vs 73.14 ± 9.22 mmHg, P < .001) blood pressures and lower LDL mass (359.55 ± 80.42 vs 374.37 ± 86.10 mg/dL, P = .009) and total cholesterol concentrations (229.51 ± 43.21 vs 235.89 ± 45.40 mg/dL, P = .04) than nonsurvivors.

conclusionLow HDL3 reduces the odds of extended survival in men, independent of HDL2, other lipoproteins, and standard risk factors.
