Different interaction of onset age and duration of type 1 diabetes on the dynamics of autoantibodies to insulinoma-associated antigen-2 and zinc transporter 8.

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
AIMS/
introductionThis study aimed to investigate the dynamics associated with autoantibodies to insulinoma-associated antigen-2 (IA-2A) and zinc transporter 8 (ZnT8A) relating to the onset age and disease duration in patients with type 1 diabetes.
methodsUsing bridging-type enzyme-linked immunosorbent assay, IA-2A, ZnT8A and glutamic acid decarboxylase autoantibodies were evaluated in 269 patients with type 1 diabetes (median onset age 18.2 years, range 0.8-86 years; median diabetes duration 7 years, range 0-58 years). We then compared the prevalence of these autoantibodies among the different age groups, along with the duration of diabetes using the Cochran-Armitage trend test and multivariate logistic regression analysis.
resultsThe prevalence of IA-2A, ZnT8A and glutamic acid decarboxylase autoantibodies in patients with duration of ≤3 years was 41.1, 36.7 and 72.2%, respectively, with 80.0% expressing one or more of these autoantibodies. This prevalence declined according to the disease duration (P < 0.005). Both IA-2A and ZnT8A were more frequently observed in younger patients, whereas glutamic acid decarboxylase autoantibodies was more common in older patients. Multivariate logistic regression analysis showed that there was a significant interaction between the onset age and duration of diabetes in patients diagnosed when aged ≤10 years regarding all anti-islet autoantibodies (P < 0.05). However, for patients diagnosed in the middle tertile (aged 11-30 years), the interaction was significant only for ZnT8A, and for those with late-onset diabetes (aged ≥31 years) only for IA-2A.
conclusionsThe current study showed that the rate of disappearance of anti-islet autoantibodies is faster in patients aged ≤10 years, and that even though both proteins are localized in the insulin granule membrane, humoral autoimmunity to IA-2 and ZnT8 differs according to the age of onset.
