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

Adipose tissue (AT) lipolysis insulin resistance results in excess free fatty acid (FFA) release. We tested the hypothesis that the ability of insulin to suppress AT lipolysis is unrelated to the ability of niacin to suppress lipolysis, because niacin acts through a different proximal signaling pathway. Ten volunteers (5 women and 5 men) with upper-body obesity and/or type 2 diabetes mellitus (T2DM) underwent two study visits with overnight intravenous infusions of niacin (1.4 mg/min) or saline, followed by a hyperinsulinemic-euglycemic clamp. FFA-palmitate Ra was measured using [U-13C] and [2H9]palmitate infusions; abdominal AT biopsies were performed before and during the insulin clamp. The suppression of FFA-palmitate Ra by insulin on the saline control day and by niacin after an overnight infusion were highly correlated (r = -0.93, P < 0.001). Fasting AT Akt (pAktS473/474-to-panAkt ratio, P = 0.01) and perilipin 1 (PLN1) (pPLN1S552-to-panPLN1 ratio, P = 0.02) phosphorylation were less during niacin treatment than in the saline control study. Because the suppression of lipolysis by insulin and niacin are highly correlated within individuals and because niacin and insulin act through different proximal signaling pathways, we propose dysregulated AT lipolysis in obesity/T2DM is due to dysfunction(s) in distal lipolysis proteins rather than isolated "insulin resistance." ARTICLE HIGHLIGHTS: We undertook this study to compare adipose tissue lipolysis responses to insulin and niacin in humans. We tested the hypothesis that adipose tissue insulin resistance would be unrelated to adipose tissue niacin resistance. The suppression of lipolysis by insulin and niacin were highly correlated. Dysregulated adipose tissue lipolysis in obesity/type 2 diabetes is due to dysfunction(s) in distal lipolysis proteins rather than isolated "insulin resistance."
