Impacts of hypothyroidism on clinical, delivery, and fetal outcomes of coronavirus disease 2019: a cross-sectional study.
Article in Revista da Associacao Medica Brasileira (1992), 2026. 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
objectiveThe aim of this study was to assess the effects of preexisting hypothyroidism on the course of coronavirus disease 2019 and on delivery and fetal outcomes in pregnant women with coronavirus disease 2019.
methodsTwo groups of pregnant women with coronavirus disease 2019 were included, that is, those with no comorbid condition and those with preexisting hypothyroidism as the sole comorbid condition. We assessed the course of coronavirus disease 2019 and delivery and fetal outcomes in the two groups.
resultsOf 167 participants, 143 had no preexisting comorbidity, and 24 had hypothyroidism as the sole comorbid condition. Patients with hypothyroidism had significantly higher incidences of severe coronavirus disease 2019 and the following coronavirus disease 2019 symptoms: shortness of breath, loss of sense of smell and/or taste, and tachypnea. Hospital (length of stay, intensive care unit admission and stay, mortality), delivery (normal vaginal delivery, cesarean section, and emergency cesarean section), and fetal (preterm, birth weight, 1- and 5-min Appearance, Pulse, Grimace, Activity, and Respiration scores, stillbirth) outcomes were similar in the two groups. The outcomes were also similar in patients with severe coronavirus disease 2019, though those with hypothyroidism had shorter hospital stay and intensive care unit stay and lower rates of intensive care unit admission, mortality, emergency cesarean section, preterm delivery, and low birth weight newborns.
conclusionOur results suggest that preexisting hypothyroidism has adverse impacts on the severity of coronavirus disease 2019 and its symptoms. Considering severe coronavirus disease 2019 cases, seemingly favorable hospital, delivery, and fetal outcomes on the part of hypothyroidism may be worth further research.
