Shifts in amino acids profile in chronic pancreatitis.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundChronic pancreatitis (CP) can lead to pancreatic exocrine insufficiency (PEI), causing protein malabsorption and altered amino acid levels. Our aim is to investigate amino acid levels in patients with CP and to assess the associations with exocrine insufficiency, pancreatic elastography, and the severity of CP.
methodsTwenty-five patients with CP were prospectively enrolled in this study. A control group included 28 age- and gender-matched subjects without pancreatic disease. Amino acids were quantified using the Biocrates MxP Quant 500 kit. Differences in amino acid levels were calculated using the non-parametric Wilcoxon test. Pancreatic stiffness was evaluated by EUS-elastography, PEI was assessed using fecal elastase-1 levels. The severity of CP was determined using the M-ANNHEIM classification.
resultsThe ratio of nonessential amino acids to essential amino acids, glutamic acid and aspartic acid levels were significantly increased in the CP group, whereas tryptophan levels were significantly decreased in CP. A positive correlation between proteinogenic amino acids and the severity of pancreatitis was found. Proline levels showed a strong correlation with the CP severity index (r = 0.63), a significant correlation with elastase-1 values (r = -0.48, p = 0.02), and a moderate correlation with pancreatic stiffness (r = 0.47, p = 0.09).
conclusionPatients with CP have altered amino acid blood levels, an increased ratio of nonessential to essential amino acids. The severity of CP was found to increase the levels of nonessential amino acids, with proline showing the strongest associations with severity, elastase-1 levels, and pancreatic stiffness.
