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

BACKGROUND/

aimsHepatic nerve innervation plays important roles in hepatic metabolism and hemodynamic mechanisms. We compared the distribution patterns of hepatic nerves between normal livers and two liver diseases to elucidate the effects of liver disease on the distribution of hepatic nerves.

methodsTissue specimens were obtained by ultrasonography-guided needle biopsies from 10 normal controls, 74 patients with chronic hepatitis (CH), and 35 patients with liver cirrhosis (LC). The obtained specimens were immunohistochemically stained using antibodies for S-100 protein and alpha-smooth-muscle actin (alpha-SMA). The degree of the expression in liver tissues was quantified by manual counting of positively stained nerve fibers under light microscopy. The serum hyaluronic acid level was assayed in all subjects to evaluate hepatic fibrosis. Electron microscopy examinations were also performed.

resultsThe hepatic nerve innervation was significantly lower in LC than in normal controls, as indicated by S-100 protein staining. alpha-SMA and hyaluronic acid levels were higher in LC and CH than in normal controls. Electron microscopy revealed that unmyelinated nerve fiber bundles in the intralobar connective tissue coursed in the vicinity of hepatic triads.

conclusionsThese results suggest that hepatic nerve innervation can be decreased by hepatic inflammatory responses and/or fibrotic changes in LC patients. Further study is needed to clarify this observation.
