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

BACKGROUND AND

aimWe recently reported mucosal infiltration of IgG4-expressing plasma cells in a patient with chronic antibiotic-refractory pouchitis (CARP). The role of serum IgG4 in the pathogenesis and clinical course of ileal pouch disorders has not been investigated. We hypothesized that IgG4-mediated autoimmunity may be a contributing factor in for CARP. The aims of the study were to investigate the prevalence of elevated serum IgG4 in symptomatic patients with ileal pouches and to characterize clinical features of pouch disorders in these patients.

methodsA total of 124 consecutive symptomatic patients with ileal pouches from our subspecialty Pouchitis Clinic were enrolled in the study from January to October 2010. Serum IgG4 was measured at the time of presentation. Demographic, clinical, and laboratory characteristics were compared between the study (with serum IgG4 ≥112 mg/dl) and control (with serum IgG4 <112 mg/dl) groups.

resultsThere were ten patients (8.0%) with high serum IgG4 in the study group, while the remaining 114 (92%) patients were in the control group. The prevalence of elevated serum IgG4 in this series was 8%. None of the patients had a confirmed diagnosis of autoimmune pancreatitis. The median serum IgG4 in the study group was 144.5 vs. 14 mg/dl in the control group. The mean age of patients in the study and control groups was 35.5 ± 14.5 and 42.0 ± 13.2 years, respectively (p = 0.137). Two patients in the study group (20.0%) had concurrent autoimmune disorders as compared to 19 patients (16.7%) in the control group (p = 0.788). Three (30.0%) patients in the study group had coexisting primary sclerosing cholangitis (PSC) in contrast to 15 (13.2%) in the control group (p = 0.147). Among the study group patients, five (50.0%) had CARP and one (10%) had Crohn's disease (CD) of the pouch, while in the control group, 23 (20.2%) had CARP and 24 (21.1%) patients had CD of the pouch (p = 0.273). CARP was more commonly seen in patients with high serum IgG4 than patients with a normal IgG4 (50.0% vs. 20.2%, p = 0.03).

conclusionsApproximately 8% of pouch patients presenting with symptoms of pouch dysfunction to our clinic had elevated serum IgG4. Patients with elevated serum IgG4 were more likely to have CARP.
