Lack of effect of experimental hypovolemia on imipenem muscle distribution in rats assessed by microdialysis.
Article in Antimicrobial agents and chemotherapy, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
The aim of this study was to investigate the influence of hypovolemia on the distribution of imipenem in muscle extracellular fluid determined by microdialysis in awake rats. Microdialysis probes were inserted into the jugular vein and hind leg muscle. Imipenem recoveries in muscle and blood were determined in each rat by retrodialysis by drug before drug administration. Hypovolemia was induced by removing 40% of the initial blood volume over 30 min. Imipenem was infused intravenously at a dose of 70 mg . kg(-1) over 30 min, and microdialysis samples were collected for 120 min from hypovolemic (n = 8) and control (n = 8) rats. The decay of the free concentrations in blood and muscle with time were monoexponential, and the concentration profiles in muscle and blood were virtually superimposed in both groups. Accordingly, the ratios of the area under the concentration-time curve (AUC) for tissue (muscle) to the AUC for blood were always virtually equal to 1. Hypovolemia induced a 23% decrease in the clearance (P < 0.05) of imipenem, with no statistically significant alteration of its volume of distribution. This study showed that imipenem elimination was altered in hypovolemic rats, probably due to decreased renal blood flow, but its distribution characteristics were not. In particular, free imipenem concentrations in blood and muscle were always virtually identical.
