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
Introduction: Although left ventricular assist device (LVAD) implantation is associated with improved survival in patients with end-stage heart failure, the impact of preoperative pulmonary function on short-term outcomes is unclear. Methods: We conducted a retrospective review of all primary LVAD implants at a single institution. Common measures of preoperative pulmonary function were evaluated. Survival was estimated using the Kaplan-Meier method. Results: From 2017-2022, 107 patients underwent primary LVAD implantation. Prior to implantation, 68 (63.6 %) were on room air, 28 (26.4 %) were on nasal cannula, 2 (1.9 %) were on noninvasive positive pressure ventilation, and 9 (8.5 %) were on the ventilator. The average preoperative fraction of inspired oxygen (FiO2) was 25.3 ± 8.2 % while the mean percentage predicted forced expiratory volume in 1 second (FEV1) was 71.4 ± 20.9 %. Overall, 1-year survival was 86.8 %, the median postoperative ventilator time was 20.4 [4.2-77.7] h, and 18 (16.8 %) patients required postoperative tracheostomy. When stratified by pulmonary function, lower FEV1 and increased preoperative FiO2 were associated with decreased 1-year survival. Conclusions: In conclusion, preoperative pulmonary function is associated with short-term LVAD survival, postoperative ventilatory time, and need for tracheostomy. Therefore, rigorous pulmonary function evaluation may help in appropriate preoperative risk stratification.
