The effect of propranolol on gastrointestinal motility and permeability in patients with cirrhosis and significant portal hypertension.

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
backgroundPatients with cirrhosis and portal hypertension may have alterations in intestinal barrier resulting in increased susceptibility for infections. We investigated the effect of propranolol in gastrointestinal motility, permeability and bacterial overgrowth in cirrhosis.
methodsPatients with cirrhosis and esophageal varices were studied before and after a build-up dose of propranolol according to standard guidelines. Serum TNF-a, IL-6, IL-1b, LPS and bacterial DNA were measured before and during propranolol therapy. Oro-caecal transit time (OCTT) and bacterial overgrowth (BO) have been evaluated with H2 breath testing. Intestinal paracellular (IP), cellular passive non-carrier (ICNC), cellular passive carrier-mediated (ICCM), and gastric permeability (GP) were evaluated by measurement of lactulose, mannitol, D-xylose and sucrose respectively in urine, with high performance liquid chromatography (HPLC).
results35 patients with cirrhosis and portal hypertension with median age was 59.6 years (range 42-86) were included in the study. Twenty one had viral hepatitis and 25 were classified as having advanced cirrhosis (Child-Pugh B: 14 or C: 11). Median dose of administrated propranolol was 40 mg/day. After 7 days propranolol treatment BO was resolved in 15 out of 16 patients (93.7%, p = 0.0001) and OCTT was reduced significantly from 180 min to 139 min (SD 58.5, difference - 4 1 min, p = 0.0001). Serum IL-6 levels were reduced in 21/35 (60%) patients from 41.1 to 19 pg/ml (p = 0.01), TNF-a in 10/35 (28.5%) patients from 10.7 to 5.6 pg/ml (p = 0.007) and LPS in 20/35 (57%) from 7.1 to 5.2 mg/L (p = 0.1). No bacterial DNA was detected in serum of all patients either baseline or under propranolol treatment. IP was significantly reduced (0.2 to 0.16, p = 0.04) whereas ICNC (p = 0.9), ICCM (p = 0.4) and GP (p = 0.7) were not affected significantly. Intestinal Permeability (PI) index (Lactulose to Mannitol ratio) was significantly reduced (0.027 to 0.02, p = 0.03).
conclusionIn patients with cirrhosis and portal hypertension, propranolol use is associated with reduction in BO, increase in intestinal motility and amelioration in intestinal permeability. Moreover IL-6 and LPS levels are being decreased in the majority of patients under propranolol.
