Post-Operative but Not Pre-Operative COVID-19 Predicts Serious Complications and Mortality Following Elective Bariatric Surgery.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeWe sought to characterize the prevalence and subsequent impact of pre- and post-operative COVID-19 diagnosis on bariatric surgery outcomes. COVID-19 has transformed surgical delivery, yet little is known regarding its implications for bariatric surgery. MATERIALS AND
methodsThe Metabolic and Bariatric Accreditation and Quality Improvement Program (MBSAQIP) database was evaluated with three cohorts described: those diagnosed with COVID-19 pre-operatively (PRE), post-operatively (POST), and those without a peri-operative COVID-19 (NO) diagnosis. Pre-operative COVID-19 was defined as COVID-19 within 14 days prior to the primary procedure while post-operative COVID-19 infection was defined as COVID-19 within 30 days after the primary procedure.
resultsA total of 176,738 patients were identified, of which 174,122 (98.5%) had no perioperative COVID-19, 1364 (0.8%) had pre-operative COVID-19, and 1252 (0.7%) had post-operative COVID-19. Patients who were diagnosed with COVID-19 post-operatively were younger than other groups (43.0 ± 11.6 years NO vs 43.1 ± 11.6 years PRE vs 41.5 ± 10.7 years POST; p < 0.001). Pre-operative COVID-19 was not associated with serious complications or mortality after adjusting for comorbidities. Post-operative COVID-19, however, was among the greatest independent predictors of serious complications (OR 3.5; 95% CI 2.8-4.2; p < 0.0001) and mortality (OR 5.1; 95% CI 1.8-14.1; p = 0.002).
conclusionsPre-operative COVID-19 within 14 days of surgery was not significantly associated with either serious complications or mortality. This work provides evidence that a more liberal strategy which employs early surgery after COVID-19 infection is safe as we aim to reduce the current bariatric surgery case backlog.
