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

Anti-thyroid peroxidase antibody (TPO-Ab), which is the known cause of autoimmune thyroid disease, enhances proinflammatory cytokine responses. Since low-grade inflammation is a known risk factor for atherosclerosis, a normal range of TPO-Ab (TPO-Ab negative) could be positively associated with atherosclerosis among participants with normal thyroid function. However, no study reported the association between normal range of TPO-Ab and atherosclerosis among eu-thyroid participants. A cross-sectional study was conducted with 1165 Japanese individuals with normal thyroid function (ie, normal range of free triiodothyronine [free T3] and free thyroxine [free T4]), aged 40 to 74 years, who participated in an annual health checkup in 2014. Among the study population, 115 were diagnosed as having atherosclerosis. A normal range value of TPO-Ab titer is revealed to be positively associated with atherosclerosis; sex, age, thyroid function (free T3 and thyroid-stimulating hormone), and known cardiovascular risk factor adjusted odds ratio and 95% confidence interval of atherosclerosis for logarithmic values of TPO-Ab was 2.23 (1.11, 4.47). When we limited the analysis to participants with normal levels of thyroid-stimulating hormone, this association became slightly stronger (2.65 [1.27,5.51]). Among the eu-thyroid general population, a normal range of TPO-Ab titer is revealed to be positively associated with atherosclerosis. Even though a TPO-Ab titer is not clinically relevant and is not associated with autoimmune thyroid disease, it could influence endothelial remodeling including atherosclerosis.
