Outcomes of Liver Cancer Patients Undergoing Elective Surgery after Recovering from Mild SARS-CoV-2 Omicron Infection: A Retrospective Cohort Study.
Article in Cancers, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
With the emergence of new virus variants, limited data are available on the impact of SARS-CoV-2 Omicron infection on surgery outcomes in cancer patients who have been widely vaccinated. This study aimed to determine whether undergoing hepatectomy poses a higher risk of postoperative complications for liver cancer patients who have had mild Omicron infection before surgery. A propensity-matched cohort study was conducted at a tertiary liver center from 8 October 2022 to 13 January 2023. In total, 238 liver cancer patients who underwent hepatectomy were included, with 57 (23.9%) recovering from preoperative SARS-CoV-2 Omicron infection and 190 (79.8%) receiving COVID-19 vaccination. Pre- and post-matching, there was no significant difference in the occurrence of postoperative outcomes between preoperative COVID-19 recovered patients and COVID-19 negative patients. Multivariate logistic regression showed that the COVID-19 status was not associated with postoperative major pulmonary and cardiac complications. However, preexisting comorbidities (odds ratio [OR], 4.645; 95% confidence interval [CI], 1.295-16.667), laparotomy (OR, 10.572; 95% CI, 1.220-91.585), and COVID-19 unvaccinated (OR, 5.408; 95% CI, 1.489-19.633) had increased odds of major complications related to SARS-CoV-2 infection. In conclusion, liver cancer patients who have recovered from preoperative COVID-19 do not face an increased risk of postoperative complications.
