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

backgroundElexacaftor/tezacaftor/ivacaftor (ETI) has dramatically changed the landscape of cystic fibrosis (CF) care, including in those who require lung transplantation. The objectives of the study were to describe the cohort demographics and outcomes of primary lung transplant recipients before and after the availability of ETI.

methodsThis is a descriptive study of lung transplants performed at the Toronto Lung Transplant Program for CF during two time periods: 2019 (pre-ETI era) and 2021-2023 (post-ETI era). All subjects were referred from the Adult CF program at St. Michael's Hospital, Toronto. Data were obtained from chart review and the Toronto Lung Transplant database. The Kaplan-Meier method was used to estimate survival probability at 1 year post-transplant.

resultsThere were 22 lung transplants performed in 2019 (19 [86.4%] primary and 3 [13.6%] re-transplants) compared to 11 lung transplants (8 [72.7%] primary and 3 [27.3%] re-transplants) in the post-ETI era. In primary transplant recipients, median age was 29.4 years (Range 18.6-67.6 years) in 2019 compared to 30.0 years (Range 19.1-64.0 years) in 2021-2023. In the post-ETI era, none of the individuals had a deltaF508 variant, compared to 84% in 2019. One-year survival probability was lower in the post-ETI era (62.5% vs. 84.2%, respectively).

conclusionLung transplant recipients in the post-ETI era were more complex with high-risk characteristics and had worse post-transplant outcomes. This study highlights the importance of further investigation to better understand the impact of ETI on transplant referral patterns, recipient characteristics, and post-transplant outcomes in the CF population.
