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.

Abstract

backgroundThe ratio of T helper 1 (Th1) to T helper 2 (Th2) as well as T helper 17 (Th17) to regulatory T cells (Treg) represents the state and direction of immune response. Recent studies demonstrated that dexmedetomidine reduced the secretion of inflammatory cytokines. We performed this study to investigate the effect of different doses of intraoperative dexmedetomidine on the expression of Th1, Th2, T17 and Treg cytokines and their ratios.

methodsSeventy-five patients undergoing laparoscopic cholecystectomy were randomly separated into one of three groups: the full dose group (n = 25), in which dexmedetomidine was infused with a 1.0 μg/kg loading followed by an infusion of 0.5 μg/kg/min after anaesthetic induction, or the half dose group (n = 26), in which the dose was half of that of full dose group, or the saline group (n = 24) which was control. T cell cytokines were quantified by sandwich enzyme-linked immunoassay for blood samples taken after anaesthetic induction (T0), at the end of surgery (T1), and 60 min after surgery (T2). IFN-gamma/IL-4 and IL-17/IL-10, which represent the ratio of Th1/Th2 and Th17/Treg cytokines, respectively, were calculated as indices of immune cell levels based upon serum cytokines levels in place of direct measurements. C-reactive protein (CRP) concentrations were measured on the next day following surgery.

resultsThe full dose group was associated with higher ratios of IFN-gamma/IL-4 than those of half dose group and control [10.1 vs. 1.9 at T1 (P = 0.041) compared with half dose group, and 10.1 vs. 0.2 at T1 (P = 0.031), 7.4 vs. 0.1 at T2 (P = 0.025) compared with control]. IL-17/IL-10 ratios were higher in the full dose group than those in control [4.2 vs. 0.6 at T1 (P = 0.013), 3.0 vs. 0.3 at T2 (P = 0.011)]. The CRP levels were lower in the dexmedetomidine-treated groups in a dose-dependent manner.

conclusionsDexmedetomidine exhibits immunomodulatory effects, shifting the Th1/Th2 and T17/Treg cytokine balance toward Th1 and T17, respectively, in a dose-dependent pattern in patients with surgical and anaesthetic stress.
