1 · What the graph read from it

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.

2 · The registry

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

Autoimmune pancreatitis is a fibroinflammatory subtype of chronic pancreatitis resulting from aberrant immune responses. Currently, there are two forms of autoimmune pancreatitis: type 1 (T1-AIP) or lymphoplasmacytic sclerosing pancreatitis and type 2, also known as idiopathic duct-centric chronic pancreatitis. T1-AIP is often identified as the pancreatic appearance of immunoglobulin 4 (IgG4)-related disease. T1-AIP commonly appears in the seventh decade of life with a considerable male predominance, frequently associated with elevations in serum IgG4 levels and IgG4-positive cells on tissue biopsy. Type 1 and 2 autoimmune pancreatitis glucocorticoid steroid treatment leads to clinical remission in almost 100% of type 1 and 2 cases. Here, we present a case of an adult who presented with an incidental pancreatic head and tail mass on CT imaging with elevated serum IgG4 levels. He was started on steroid therapy with eventual clinical remission of his disease. This case highlights the rarity of autoimmune pancreatitis and the work-up required to rule out malignancy of the pancreatic mass.
