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
objectivesThe present study aimed to determine whether intestinal epithelial cell (IECs) apoptosis could be induced by endoplasmic reticulum stress (ERS) in severe acute pancreatitis (SAP), and the role of chemical chaperone 4-phenylbutyric acid (4-PBA) in SAP-associated intestinal barrier injury.
methodsTwenty-four male Sprague Dawley rats were randomly divided into three groups: the sham operation group, the SAP group, and the SAP model plus 4-PBA treatment group (4-PBA group). A rat model of SAP was induced by retrograde injection of 5% sodium taurocholate (STC) into the biliopancreatic duct; in the 4-PBA group, 4-PBA was injected intraperitoneally at a dose of 50 mg/kg body weight for 3 days before modeling.
resultsThe results indicated that 4-PBA attenuated the following: (1) pancreas and intestinal pathological injuries, (2) serum TNF-α, IL-1β, and IL-6, (3) serum DAO level, serum endotoxin level, (4) the apoptosis of IECs, (5) ER stress markers (caspase-12, CHOP, GRP78, PERK, IRE1α, ATF6) and caspase-3 expression in intestinal. However, the serum AMY, LIPA levels, and the expression of caspase-9, caspase-8 were just slightly decreased.
conclusionsERS may be considered a predominant pathway, which is involved in the apoptosis of IECs during SAP. Furthermore, 4-PBA protects IECs against apoptosis in STC-induced SAP by attenuating the severity of ERS.
