1 · What the graph read from it

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.

2 · The registry

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

BACKGROUND COVID-19 significantly impacted the outcomes of patients, particularly those with comorbidities, including solid organ transplant recipients. The aim of this study was to investigate the incidence and mortality of COVID-19, as well as to identify independent risk factors associated with COVID-19-related death in patients undergoing orthotopic heart transplantation (OHT). MATERIAL AND METHODS The study followed 556 heart transplant recipients at a high-volume transplant center in Poland from March 2020 to March 2024. Patients were classified as infected based on a positive result from reverse transcription-polymerase chain reaction (RT-PCR) tests or SARS-CoV-2 antigen rapid tests performed on nasopharyngeal swab samples. RESULTS In the analyzed cohort, 189 of 556 patients (33.99%; 40 women, 21.16%) were diagnosed with COVID-19 following OHT. In total, 15 patients (7.94%) experienced recurrent SARS-CoV-2 infections, with 1 patient being diagnosed 3 times. A total of 33 patients (5.94%) required hospitalization due to COVID-19. Among the entire study cohort, 75 patients (13.49%) died, with 18 of these deaths (24%) directly attributable to COVID-19. In the multivariable analysis, vaccination against COVID-19 was identified as a protective factor against death due to the virus (OR, 0.22; 95% CI, 0.07-0.68; P=0.009) while increasing age was associated with a higher risk of mortality (OR, 1.08; 95% CI, 1.02-1.14; P=0.008). CONCLUSIONS The lack of COVID-19 vaccination and advanced age significantly influenced the COVID-19-related mortality risk.
