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: The coronavirus disease-2019 (COVID-19) pandemic posed pronounced challenges in the care of lung transplant (LTx) recipients. Global variations in containment strategies and the introduction of messenger ribonucleic acid (mRNA) vaccines have sparked extensive debate in both scientific and public arenas. Methods: This retrospective study compared outcomes among LTx recipients in Denmark, which implemented a more restrictive COVID-19 containment strategy, and Sweden, which adopted a less restrictive approach. A total of 318 LTx recipients with at least 1 episode of polymerase chain reaction (PCR)-confirmed COVID-19 were included. Propensity score weighting was applied to balance covariates, and survival outcomes were analyzed using weighted Cox proportional hazards and Kaplan-Meier analyses. Results: No significant differences in mortality or risk of chronic lung allograft dysfunction (CLAD) were found between countries (hazard ratios [HR] for death, Sweden = 1.49, 95% confidence intervals [CI]: 0.68-3.26, Conclusions: Despite differences in timing of infections and case load between Sweden and Denmark, clinical outcomes among infected LTx recipients were comparable. mRNA vaccination was strongly associated with improved survival. The results of the current study highlight the importance of continued vaccination efforts and tailored containment strategies in vulnerable populations.
