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
purposeUnderstanding the relationship between antithyroperoxidase antibodies (TPOAb) and carotid intima-media thickness (cIMT) could provide insights into the mechanisms linking thyroid autoimmunity and cardiovascular disease. We aimed to explore the association of multiple categories of TPOAb with the increased cIMT at baseline and at follow-up in participants from the ELSA-Brasil Study.
methodsThis prospective cohort study analyzed data from 9,264 participants (51.5 ± 8.9 years old, 55.9% women) without a history of cardiovascular disease. Fasting serum TPOAb levels were determined. Values of cIMT equal to or above one deviation standard of the sample's mean were classified as increased cIMT at baseline. The increased cIMT after the 8-year follow-up was calculated after excluding participants with increased cIMT at baseline. Multivariate analyses were done using binary logistic and Poisson regression models.
resultsThe increased cIMT was prevalent in 14.3% of the participants at baseline and its development occurred in 16.8% participants during the cohort. After adjustment for all confounder variables, TPOAb detectability (OR = 1.84, 95%CI = 1.21-2.79), and low detectable (OR = 1.81, 95%CI = 1.18-2.75), high detectable (OR = 2.01, 95%CI = 1.29-3.11) and positive (OR = 1.70, 95%CI = 1.07-2.70) TPOAb were positively associated with increased cIMT at baseline. The associations of low and high detectable TPOAb and increased cIMT at baseline were consistent when excluding those with thyroid dysfunction. There was no statistically significant association between TPOAb levels and increased cIMT at follow-up (p > 0.05), neither for all sample nor for euthyroid individuals.
conclusionDifferent levels of TPOAb, including its detectability, were associated with increased cIMT at baseline in the studied sample. We highlight that may be relevant to consider the levels of TPOAb detectability as possible marker of increased cardiovascular risk.
