A pilot study to evaluate the effect of splanchnic nerve stimulation on body composition and food intake in rats.
Article in Obesity surgery, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSystemic sympathetic stimulation with caffeine and ephedrine increased metabolic rate, reduced food intake, and improved body composition but had systemic adverse events. We hypothesize that selective sympathetic stimulation of the upper gastrointestinal tract will preserve the advantages of systemic sympathetic stimulation without its adverse events. This study evaluated the effect of splanchnic nerve stimulation on metabolic rate, food intake, and body composition.
methodsSixteen Sprague Dawley rats had monopolar electrodes placed on the superior common splanchnic nerve innervating the celiac ganglia. An indifferent electrode was placed subcutaneously on the back. The animals were placed on a 60% fat diet, and eight rats were stimulated for 6 weeks. The stimulation was advanced over 3 days from 0.6 mA to 3 mA. Metabolic rate and food intake were measured daily; weight change was monitored weekly, and body composition was determined by nuclear magnetic resonance (NMR) at the end of the study. Four of the eight animals had metabolic rate measured three times over 2-day periods at 0 mA, 1 mA, and 3 mA of stimulation in a metabolic chamber.
resultsExcept for the first week of stimulation, there was no difference in body weight between the stimulated and control groups. Cumulative food intake was less in the stimulated group (p<0. 001). The lean-to-fat ratio was greater in the stimulated group (p<0. 01), and the animals that received incremental stimulation showed significantly augmented metabolic rate (p<0. 02).
conclusionsSplanchnic nerve stimulation decreased food intake, increased metabolic rate, and improved body composition.
