Association of micronutrient status with thyroid function in adolescent Afghan refugees; a cross-sectional study.

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
Micronutrients play a crucial role in several metabolic processes including thyroid hormone metabolism and functions. The current study aimed to assess the associations between thyroid hormone levels and micronutrient status in a cohort of adolescents Afghan refugees residing in a refugee camp in Pakistan. A randomised, community based, cross-sectional study design was employed to recruit 206 adolescent (both male and female) Afghan refugees aged 10-19 years. Sociodemographic data, anthropometric assessments and blood samples were collected using standard methods. Serum vitamins, minerals and thyroid hormones levels were assessed using ELISA, electrochemiluminescence and inductively coupled plasma mass spectrometry (ICP-MS) respectively. Overall results showed the median levels of T3 and TSH were significantly higher (p < 0.05) in younger adolescents (10-14 years) compared to 15-18 year olds while T4 was significantly higher in boys compared to girls. Correlational analysis between serum micronutrients status (vitamin D, vitamin B12, ferritin, folate, zinc, copper, selenium) and thyroid hormones revealed significant relationships in different age groups. Overall, vitamin D exhibited a statistically significant positive correlation with T4 (r = 0.279) in the combined, younger (r = 0.277) and older (r = 0.319) age groups. In contrast, a statistically significant but negative correlation was observed when zinc levels were compared with T3 (r=-0.288) in the older age group and with T4 (r=-0.195) in the younger age group. In conclusion, micronutrients status, especially vitamin D and zinc, have important implications for thyroid health and thereby require close monitoring in any thyroid deficiency related disorders in vulnerable population such as refugees.Clinical trial number: Not applicable.
