Association between antinuclear antibody seropositivity and telomere length: a nationwide population-based study.
Article in Clinical and experimental rheumatology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesTelomere shortening is a well-established marker of biological aging. Whether telomere erosion coincides with age-related increases in antinuclear antibody (ANA) seropositivity remains unknown. Our study aimed to determine the association between ANA seropositivity and shortened telomeres among 1999-2002 National Health and Nutrition Examination Survey (NHANES) subjects.
methodsWe performed a cross-sectional analysis of 2,188 NHANES study participants with available ANA and telomere length data. ANA testing was performed using indirect immunofluorescence. Telomere lengths were measured via quantitative polymerase chain reaction methods. Applying appropriate sample weighting techniques, we used univariate and multivariate logistic regression methods to assess the association between shortened telomeres (i.e. lowest decile of the cohort) and ANA seropositivity.
resultsANAs were positive in 322 out of 2,188 (14.7%, 95% CI 13.3-16.3%) individuals. Subjects with shortened telomeres were more likely to be older (p<0.001), male (p=0.005), and have a cancer history (p<0.001). A higher proportion of non-Hispanic white participants (61.6% vs. 49.3%) and a lower proportion of non-Hispanic black participants (7.8% vs. 17.9%) had shortened telomeres (p<0.001). Shortened telomeres were not independently associated with ANA seropositivity (OR 1.48, 95% CI 0.87-2.52, p=0.14). However, female sex (OR 1.91, 95% CI 1.23-2.96, p=0.006), age ≥80 years (OR 2.06, 95% CI 1.08-3.92, p=0.03), and African American race (OR 1.58, 95% CI 1.00-2.51, p=0.05) were independent risk factors for ANA seropositivity. Neither sex nor race modified the relationship between ANA seropositivity and telomere length.
conclusionsTelomere erosion does not appear to be responsible for age-related increases in the prevalence of ANA seropositivity.
