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
backgroundPostoperative pancreatic fistula (POPF) is one of the most harmful complications after pancreatic resection. Efficient drainage affects the clinical outcome of POPF. Inefficient drain of the fluid collection should contribute greatly to the need of additional interventional drainage, secondary morbid complications, and death.
methodsA rat model of POPF was established by distal pancreatosplenectomy. A novel active drain system (ADS) for POPF was developed by wrapping polyvinyl alcohol sponges (PVA) to an end of the drainage tube. Passive drain system (PDS), ADS and ADS with PVA were used for POPF in rat models. The volume and amylase of ascites were measured. CT scan was applied to assess abdominal fluid collection. Rats pancreatic transection stumps were stained by hematoxylin and eosin (H&E).
resultsThe volume of drainage of ADS with PVA group was less than that of PDS group and ADS group at late stage. CT scan showed obvious abdominal fluid collections in 2/8, 2/8 and 0/8 rats in PDS, ADS and ADS with PVA group separately. Macrofindings showed significant intra-abdominal adhesions and inflammation in PDS and ADS group but not in ADS with PVA group. H&E staining showed less inflammatory cells and destroyed pancreatic glands in ADS with PVA group.
conclusionADS with PVA drained ascites effectively in the rat model of POPF. The effective drainage of pancreatic juice reduced the inflammation of abdominal organs and pancreatic resection stumps, and might promote the healing of POPF.
