Thyroid function in pregnant Saudi women: A cross-sectional study at a tertiary hospital.
Article in Journal of family & community medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThyroid dysfunction during pregnancy can have significant implications for both maternal and fetal health. The physiological changes of pregnancy, including increased thyroxine-binding globulin and human chorionic gonadotropin-mediated thyroid-stimulating hormone (TSH) suppression, alter thyroid hormone concentrations and highlight the need for population-specific reference ranges. This study aimed to characterize trimester-specific thyroid function patterns and hypothyroidism in Saudi pregnant women. MATERIALS AND
methodsThis cross-sectional study was conducted among Saudi women who delivered singleton live births during January1 and December31, 2023 at a tertiary care hospital in Riyadh, Saudi Arabia. A random sample of 329 women meeting the inclusion criteria was selected from a total of 2259 women who delivered during the study period. Data regarding patient demographic characteristics, thyroid disease history, TSH levels, thyroid peroxidase antibody (TPO-Ab) status, and the use of levothyroxine was abstracted from hospital's electronic health record system using a structured data collection sheet. Data were analyzed using SPSS; Categorical variables were summarized as frequencies and percentages, whereas mean and standard deviation was calculated for continuous variables. Categorical variables were summarized as frequencies and percentages. Thyroid function parameters were compared across clinical groups using ANOVA or Kruskal-Wallis test, as appropriate.
resultsThyroid dysfunction was identified in 27.4% of the 329 Saudi pregnant women; 21.6% of these were subclinical, and 5.8% were overt hypothyroidism. Median TSH concentrations were 2.03, 2.46, and 2.26 mIU/L across the first, second, and third trimesters, respectively. The mean TSH levels differed significantly across thyroid function groups in all trimesters (
conclusionA notable proportion of Saudi pregnant women exhibited thyroid dysfunction, underscoring the importance of locally derived trimester-specific TSH data. These findings provide useful baseline information that could guide future multicenter or prospective studies and support the refinement of thyroid screening practices in Saudi Arabia.
