Proteases and protease inhibitors in taurocholate-induced acute pancreatitis in rats.

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
conclusionTaurocholate-induced acute pancreatitis (AP) in the rat mimics early necrotizing human pancreatitis. Protease activation and protease inhibitor consumption occur consistent with a two-stage development, and contact-phase activation is a possible primary event in this model.
backgroundProteases and protease inhibitors have been indicated to play an important role in both human and experimental acute pancreatitis, although little is known about them in rats.
methodsThree percent sodium taurocholate was infused into the bilio-pancreatic duct to induce AP, and over 0-72 h we measured lipase, amylase, albumin, prekallikrein, factor X, alpha-1-macroglobulin, alpha-2-antiplasmin, antithrombin III, alpha-1-protease inhibitor, and C1-esterase inhibitor (all in plasma) and histologic and macroscopic findings.
resultsA severe necrotizing, nonlethal, AP was induced with an early increase in plasma lipase and alpha-amylase activity levels and peritoneal exudate followed by a return to near control levels after 72 h. Histologic score and pancreatic wet weight ratio increased initially and remained high during the observation period. The protease inhibitors C1-esterase inhibitor, alpha-2-antiplasmin, and antithrombin III decreased early, within 0-6 h, whereafter levels normalized. The protease inhibitors alpha-1-macroglobulin and alpha-1-protease inhibitor later gradually decreased over the 72 h.
