Institutional case volumes of thyroidectomies in Brazil and the impact of the COVID-19 pandemic: insights from a national database.
Article in Archives of endocrinology and metabolism, 2024. 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
Introduction: Providing widespread access to thyroidectomies while consolidating services in high-volume centers is a significant challenge in healthcare. In this context, from a national perspective, we aimed to analyze the impact of the COVID-19 pandemic on the institutional case volumes of thyroid surgery in Brazil. Material and methods: We analyzed retrospective thyroidectomy data from the Department of Informatics of the Unified Health System (Datasus), stratifying institutions into low-volume, intermediate-volume, and high-volume centers (<10, 10-100, and >100 thyroidectomies/year, respectively). We assessed the differences in absolute numbers and percentages of thyroidectomies performed during the pandemic years (2020-2022) compared with the pre-pandemic year (2019). Differences in the proportion of institutions based on case volumes from 2019 to 2022 were assessed using Cochran's Q test. Results and discussion: In 2019, 556 Brazilian institutions performed 15,331 thyroidectomies. Of these, 46.4% were categorized as low-volume, 48.4% as intermediate-volume, and 5.2% as high-volume institutions, accounting for 5.5%, 61.4%, and 33.1% of the thyroidectomies, respectively. Compared with 2019, the volume of thyroidectomies was lower by 41.2% in 2020, 37.0% in 2021, and 12.8% in 2022. When analyzing the proportions of institutions that maintained their pre-pandemic case volume in the first pandemic year, the intermediate and high-volume institutions experienced reductions of 34.9% (p < 0.001) and 58.6% (p < 0.001), respectively, while low-volume institutions presented a 4.3% reduction (p = 0.081). Conclusion: The COVID-19 pandemic disrupted the landscape of thyroidectomies in Brazil, particularly affecting intermediate-volume and high-volume institutions, while low-volume institutions showed greater resilience.
