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
objectiveTo analyze changes in surgical volume across different specialties in Brazil before, during, and after the COVID-19 pandemic.
methodsThis descriptive observational study compared surgical volumes for the specialties with the highest number of procedures each year from 2019 to 2023. Data were sourced from the Department of Informatics of the Unified Health System (DATASUS - TabNet).
resultsA total of 2,117,383 surgical procedures across 13 operation types were analyzed. Between 2019 and 2020, surgical volume declined by 35%, with reductions ranging from -1% to -54% depending on the procedure. Although volumes increased by 2023, this was insufficient to address the backlog of delayed surgeries. Otorhinolaryngology and urology were the most affected specialties, while cholecystectomy saw a net post-pandemic increase.
conclusionThe COVID-19 pandemic significantly disrupted all analyzed surgical procedures in Brazilian Public Health System, resulting in a 35% overall decline. Despite partial recovery, the persistent surgical deficit remains a major challenge, reflecting patterns observed internationally.
