Expression of hepatic lipid droplets is decreased in the nitrofen model of congenital diaphragmatic hernia.

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
backgroundPrenatal mortality in newborn infants with congenital diaphragmatic hernia (CDH) has been attributed to increased amounts of liver hernia ion through the diaphragmatic defect. Antenatal studies in human and rodent fetus with CDH further demonstrated a contribution of the developing liver in the pathogenesis of CDH. The abnormal hepatic growth in experimental animal models, therefore, indicates a disruption of normal liver development in CDH. However, the underlying structural, histological and functional changes in the liver of animals with CDH remain unclear. We design this study to test the hypothesis that the morphological and cellular liver development is altered in the nitrogen-induced CDH model.
methodsPregnant rats were exposed to either olive oil or nitrofen on day 9 of gestation (D9). Livers and chest were harvested on D21 and divided into two groups: control (n = 8), nitrofen with CDH (CDH, n = 8). Haematoxylin-eosin (Straub et al. Histopathology 68:617-631, 2013) staining was performed to evaluate underlying morphological changes. Apoptosis was checked by using TUNEL staining and apoptotic cell number was counted on 16-16 slides in 25 fields by two independent viewers. Hepatic lipid droplet expressions were evaluated by hepatic adipose differentiation-related protein (ARDP) expression.
resultsCompared to controls markedly increased hypertrophy was seen in CDH group. Significantly increased apoptotic cell numbers were detected in CDH group compared to controls (5.1 ± 1.5 vs 2.1 ± 0.6) (p < 0.05). The relative mRNA expression levels of ARDP were significantly reduced in CDH group compared to controls. Immunohistochemistry showed markedly decreased hepatic ADRP immunoreactivity in CDH fetuses compared to controls.
conclusionsOur findings provide strong evidence of hepatic hypertrophy and increased cell apoptosis in the liver of nitrofen-induced CDH. These morphological changes may affect liver lipid droplet expression function.
