Correlation of C-reactive Protein, Lactate Dehydrogenase, and Serum Calcium With the CT Severity Index in Acute Pancreatitis.

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
Background Acute pancreatitis exhibits a wide clinical spectrum ranging from mild, self-limiting disease to severe forms associated with significant morbidity and mortality. Early identification of disease severity is crucial for guiding management and triaging patients who require close monitoring or intensive care. Biochemical markers that are simple and readily available may aid in early severity prediction. Methodology This prospective study included 55 adult patients diagnosed with acute pancreatitis and treated in the Department of General Surgery at Sri Ramachandra Institute of Higher Education and Research between November 2020 and November 2021. Patients with chronic pancreatitis, recurrent pancreatitis, or pancreatic malignancy were excluded. All patients underwent biochemical evaluation including C-reactive protein (CRP), lactate dehydrogenase (LDH), and serum calcium, along with contrast-enhanced CT of the abdomen using a pancreatic protocol. The CT severity index (CTSI) was calculated, and correlations with biochemical parameters were analyzed. Results Of the 55 patients, alcohol was the etiology in 40 (72.7%) patients and gallstones in 15 (27.3%) patients. A statistically significant correlation was observed between CRP levels and the CTSI, as well as between LDH levels and the CTSI. No statistically significant correlation was found between serum calcium levels and the CTSI. Conclusions CRP and LDH are useful biochemical markers for predicting the severity of acute pancreatitis when correlated with the CTSI. Serum calcium did not demonstrate a significant association with disease severity in this study. These markers may assist in early risk stratification, although larger multicenter studies are required to validate these findings.
