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

backgroundFrailty is increasingly recognized as a marker of biological vulnerability associated with adverse clinical outcomes. Lung transplant recipients may be particularly susceptible to frailty, yet its impact on longitudinal pulmonary function improvement after transplantation remains poorly understood.

methodsProspective longitudinal study (2-years follow-up) in lung transplant recipients. Physical frailty was assessed using the Fried phenotype. Pulmonary function parameters (vital capacity-VC, forced vital capacity-FVC, forced expiratory volume in 1 s-FEV1, and total lung capacity-TLC) were expressed as percentage of predicted values. Linear mixed-effects models were used to evaluate the association between baseline frailty burden and pulmonary function trajectories over time, adjusting for age, sex, body mass index, underlying respiratory disease category, and time from transplantation to baseline assessment.

resultsA total of 155 lung transplant recipients were included (mean age 48.7 ± 13.3 years; 43.2% female). According to the Fried phenotype, 43.7% were robust, 40.4% pre-frail, and 15.9% frail. Higher frailty burden was independently associated with lower baseline FVC, with borderline associations for VC and FEV1. Significant frailty-by-time interactions were observed for VC (β = 2.03, p = 0.010) and FVC (β = 2.20, p = 0.003), indicating steeper longitudinal improvement in spirometric values among participants with higher baseline frailty burden. A similar trend was observed for FEV1. Reduced handgrip strength and unintentional weight loss were the frailty components most consistently associated with pulmonary function trajectories.

conclusionsThese findings support the potential role of frailty assessment in identifying vulnerable transplant recipients who may benefit from personalized rehabilitative and multidimensional post-transplant interventions.
