Evaluation of Thyroid Hormone Levels and Urinary Iodine Concentrations in Koreans Based on the Data from Korea National Health and Nutrition Examination Survey VI (2013 to 2015).
Review in Endocrinology and metabolism (Seoul, Korea), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
No nationwide data have been published about thyroid hormone levels and urinary iodine concentrations (UICs) in Korea. The Korea Centers for Disease Control and Prevention and the Korean Thyroid Association established a project to evaluate the nationwide thyroid hormone profile and UICs in healthy Koreans as part of the Korea National Health and Nutrition Examination Survey (KNHANES) VI (2013 to 2015), a nationwide, cross-sectional survey of the Korean population that enrolled 7,061 individuals who were weighted to represent the entire Korean population. Based on the KNHANES VI, the geometric mean value of serum thyroid stimulating hormone was 2.16 mIU/L, and its reference interval was 0.59 to 7.03 mIU/L. The mean value of serum free thyroxine was 1.25 ng/dL, and its reference interval was 0.92 to 1.60 ng/dL. The median UIC in the Korean population was reported to be 294 μg/L, corresponding to 'above requirements' iodine intake according to the World Health Organization recommendations. A U-shaped relationship of UIC with age was found. The prevalence of overt hyperthyroidism and overt hypothyroidism in the Korean population based on the KNHANES VI was 0.54% and 0.73%, respectively.
