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

backgroundBased on reports from tertiary care centers, chronic pancreatitis (CP) is considered to be a painful and debilitating disease frequently requiring invasive interventions. Our primary aim was to assess the natural course of CP in a population-based cohort using endoscopic and surgical interventions as surrogates for disease aggressiveness.

methodsWe identified all patients (n = 89, alcoholic [ACP = 46], non-alcoholic [NACP] = 43) with newly diagnosed definite CP from Olmsted County, Minnesota between 1977 and 2006. Patients were followed until death or censoring. Medical records were reviewed at time of diagnosis and during each follow-up. Both lifetime proportions and cumulative incidence since the initial manifestation of CP were estimated and compared. Survival was estimated with Kaplan-Meier methodology.

resultsMedian age at CP diagnosis was 56 years (IQR, 48-67) and 56% were male. During median follow-up of 10 years, 68 (76%) experienced pancreatic pain, but only 27 (30%) needed any invasive therapeutic intervention: 23% had endotherapy and 11% had pancreatic surgery. During the clinical course, when compared with NACP, ACP patients had significantly more (all p < 0.05) pain (87 vs. 65%), recurrent acute pancreatitis (44 vs. 23%), pseudocysts (41 vs. 16%), cumulative incidence of exocrine insufficiency (60 vs. 21%), and annual hospitalizations after CP diagnosis (0.79 vs. 0.25). The cumulative risk of diabetes, calcifications, surgery and overall survival was similar in ACP and NACP.

conclusionsOur study suggests that CP at a population level may have a milder course than that reported from tertiary centers. We confirm that ACP has a more severe phenotype than NACP.
