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 effects of all-trans-retinoic acid (ATRA) administration on the concentration of retinoids (RA and vitamin A) in liver, oxidative stress and the hepatic injury in a rat model of common bile duct ligation (CBDL)-induced liver injury were investigated. Female rats were subjected to a sham (n=5) or CBDL (n=48). Two weeks after operation, rats undergoing CBDL were randomized to receive treatment with either ATRA at three different doses (0.1, 1.5, 7.5 mg/kg) dissolved in bean oil or only bean oil every day over a 4-week experimental period. Rats were killed and blood samples were collected from the heart for determination of the serum transaminase. The contents of retinoids in rat liver were detected by using HPLC. Malondialdehyde (MDA), glutathione (GSH) and superoxide dismutase (SOD) levels in liver were determined by a spectrophotometric method according to the instruction of the kits. Liver pathologic changes were observed under the light microscopy and electron microscopy. The results showed that compared with sham-operated group, the levels of retinoids in the liver tissue were significantly decreased in the CBDL group (P<0.01). ATRA (0.1 mg/kg) administration in CBDL rats partially restored the contents of retinoids (P<0.05). Liver RA and vitamin A contents in CBDL group were significantly increased after ATRA (1.5 and 7.5 mg/kg) supplementation as compared with sham-operated group (P<0.05). However, in ATRA-treated CBDL group, hepatic GSH level and SOD activity, depressed by CBDL, and hepatic MDA level, increased by CBDL were returned to those in sham-operated group (P<0.05). The histologic observation of liver tissues indicated that ATRA treatment notably alleviated hepatocellular swelling, steatosis, the swelling of mitochondria and proliferation of smooth endoplasmic reticulum (SER). Treatment with ATRA could reduce levels of serum transaminase as compared with sham-operated group, more greatly in 1.5 and 7.5 mg/kg ATRA-treated groups than in 0.1 mg/kg ATRA-treated group. It was concluded that ATRA treatment can recover MDA and GSH levels and SOD activity in CBDL rat liver through restoring RA and vitamin A contents, and eventually ameliorate liver injury.
