Expression of endocrine autoantibodies in chronic hepatitis C, before and after interferon-alpha therapy.
Article in Journal of endocrinological investigation, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Interferon-alpha (IFN-alpha) treatment for chronic hepatitis C (CHC) has been associated with thyroid autoimmunity and/or dysfunction. Only a few data concerning the prevalence of islet-cell or adrenal cortex autoantibodies in IFN-alpha-treated subjects are currently available. The aims of our study were to evaluate in CHC, 1) the prevalence and association of thyroid, islet-cell and adrenal autoantibodies, and 2) the appearance of endocrine dysfunction, before and after a 6 month IFN-alpha treatment. We analyzed serum samples from 203 adult patients at the time of clinical diagnosis of CHC and showed that the prevalence of thyroperoxidase (TPOAb), thyroglobulin (TGAb), TSH-receptor (TRAb), glutamic acid decarboxylase (GAD65Ab), IA-2/ICA512 (IA-2/ICA512Ab) and 21-hydroxylase (21OHAb) autoantibodies was similar to that observed among healthy control subjects of similar age and sex distribution. Among 99 patients with follow-up serum samples, 83 accepted and 16 refused IFN-alpha treatment. The IFN-alpha treatment was associated with increase of TPOAb levels in 3 subjects already positive at baseline, with progression to overt hypothyroidism in 2 of them. The de novo appearance of autoantibodies was observed in 5/80 (6%) cases for TPOAb, 1/81 (1.2%) for GAD65Ab and 2/81 (2.5%) for IA-2/ICA512Ab. Clinical or subclinical signs of either hyperthyroidism or hypothyroidism were demonstrated in 3/5 cases with de novo appearance of TPOAb. Four subjects, initially positive for either GAD65Ab or IA2/ICA512Ab, were all found negative after IFN-alpha-treatment. No subjects showed positivity for 21OHAb either at baseline or after the follow-up period. Our study suggests that, in CHC untreated patients, the prevalence of endocrine autoantibodies is similar to that observed in the general population. Furthermore, we demonstrate that IFN-alpha treatment is associated with the induction or enhancement of thyroid, but not of islet-cell or adrenal cortex autoimmunity.
