Exploring the Correlation Between Varied Serum Iodine Nutritional Levels and Anti-Thyroglobulin Antibodies.

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
Iodine deficiency results in elevated thyroglobulin (Tg) concentrations, with high iodine Tg being more immunogenic than low iodine Tg. The study investigated the correlation between serum iodine concentration and thyroglobulin autoantibody (TgAb) levels across diverse iodine nutritional statuses as determined by urine iodine concentration (UIC). Demographic information was collected from 1,482 participants through a questionnaire. Blood and spot urine were collected to measure thyroid-stimulating hormone (TSH), TgAb, thyroid anti-peroxidase antibody (TPOAb), serum iodine (SIC), serum non-protein-bound iodine (snPBI), urine iodine (UIC), creatinine (UCr). The median UIC and SIC were 146.5 μg/L and 74.9 μg/L, respectively. A linear relationship was observed between SIC, snPBI, and serum-protein-bound iodine (sPBI) (P < 0.001). The 90% reference intervals for SIC, snPBI, and sPBI were 50.7-120.7 μg/L, 21.9-52.9 μg/L, and 19.7-77.9 μg/L, respectively. The prevalence of elevated TgAb levels was significantly higher in women than in men (P < 0.001). Both low and high levels of snPBI and sPBI were associated with an increased risk of elevated TgAb levels. In women, the risk of positive TgAb in the group below the reference value of snPBI (OR = 2.079, 95%CI: 1.166, 3.705) and sPBI (OR = 2.578, 95%CI: 1.419, 4.684) was higher. In men, the risk of positive TgAb in the group below the reference value of SIC was higher (OR = 3.395, 95%CI: 1.286, 8.962). Iodine might exert an influence on TgAb levels through its binding to proteins, primarily Tg, thereby altering the iodine content of Tg. The interplay of gender factors further enhanced the risk of TgAb emergence.
