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

objectivesThis study aimed to investigate the dynamic trends in total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) levels with ageing.

designA Chinese population-based cross-sectional study.

settingA physical examination centre of a general hospital.

participantsAdult subjects (178 167: 103 461 men and 74 706 women) without a known medical history or treatments that affect lipid metabolism.

main outcome measuresDynamic trends in the above-mentioned lipid parameters with ageing were explored; turning points of age were established using age stratification and validated by fitted multivariate linear regression modelling.

resultsAge was found to be an independent factor extensively associated with lipid levels in both sexes when adjusted for serum glucose, body mass index, lifestyle, drinking and smoking. Age was positively associated with TC, logarithm-transformed TG (LnTG) and LDL-C levels in men ≤40, ≤40 and ≤60 years old (yo) and in women ≤60, ≤70 and ≤60 yo, respectively. Conversely, age correlated negatively with TC, LnTG and LDL-C levels in men ≥61, ≥41 and ≥61 yo and in women ≥61, ≥71 and ≥61 yo, respectively. TC, TG and LDL-C levels in women were initially lower than those in men but surpassed those in men in 51-55, 61-65 and 51-55 yo age groups. The trends in HDL-C levels with age were relatively irregular, although HDL-C levels in women were higher than in men for all age groups.

conclusionsThe definition of dyslipidaemia, the atherosclerotic cardiovascular disease risk assessment and the initiation/goals of statin therapy should fully consider age-related trends in lipid levels and sex differences.
