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

objectiveIncreased free fatty acids (FFAs) are leading candidates in the pathogenesis of insulin resistance and hypertension in obese subjects. We evaluated the effect of sustained elevations of FFA on blood pressure, endothelial function, insulin secretion, inflammatory markers, and renin-angiotensin system. RESEARCH DESIGN AND

methodsTwenty-four obese, African-American, normotensive diabetic subjects received a sequential 48-h infusion of Intralipid (20%, 40 ml/h) plus heparin (250 units/h) or normal saline (40 ml/h) plus heparin (250 units/h).

resultsBlood pressure was significantly increased within 4 h of lipid infusion and reached a peak increment of 13 mm Hg in systolic and 5 mm Hg in diastolic blood pressure at 24 h (P < 0.01). Compared to baseline, lipid infusion reduced flow-mediated dilatation by 11% at 24 h and 18% at 48 h (P < 0.001). FFA and triglyceride levels increased from a baseline of 0.5 +/- 0.2 mmol/liter and 135 +/- 76 mg/dl to 1.8 +/- 1.0 mmol/liter and 376 +/- 314 mg/dl at 48 h, respectively (P < 0.01). C-Reactive protein increased by 35% at 24 h and by 110% at 48 h of lipid infusion. There were no significant changes in plasma renin and aldosterone levels during lipid or saline infusions.

conclusionIncreased FFA levels result in a rapid and sustained elevation in blood pressure, impaired endothelial function, and increased inflammatory markers in obese subjects with type 2 diabetes. The model of FFA-induced hypertension may be useful in examining disease mechanisms associated with the development of hypertension in obese subjects.
