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
Background and Aims: Evaluation of pulmonary function by spirometer in adult patients undergoing cardiac surgery is a simple test to assess pulmonary reserve that has important implications in operative morbidity. However, there is no established consensus regarding which patients should undergo preoperative pulmonary function tests (PFTs), including forced expiratory volume in the first second (FEV1) and forced vital capacity (FVC). The primary aim was to evaluate the outcome of preoperative PFTs on patients undergoing rheumatic mitral valve surgery. Material and Methods: One hundred patients undergoing rheumatic mitral valve surgery, meeting the inclusion criteria, were included in this prospective observational study. The pulmonary function of the patients was assessed using a spirometer before surgery. Preoperative pulmonary artery systolic pressure (PASP) and arterial blood gas (ABG) analyses were also performed. The correlation of PFTs with early postsurgical outcome, comprising mortality within 30 days of surgery and morbidity defined as the existence of at least one of the postoperative complications, such as low cardiac output state indicated by increased requirement of inotropes, prolonged ventilation (>24 hours), postoperative new-onset hemodynamically significant arrhythmias, renal dysfunction, and post-op infection, was assessed. Results: With the increasing New York Heart Association (NYHA) class of the patient, there was a decline of FEV1% and FVC%, which was statistically significant ( Conclusions: Preoperative lung function has an implication on intraoperative morbidity during cardiac surgery although a common consensus on its application is lacking. Preoperative spirometry can be one of the parameters for predicting postoperative morbidity and mortality in patients undergoing rheumatic mitral valve surgery. Spirometry might have a role to play in predicting patient outcomes in rheumatic mitral valve surgeries; however, larger well-powered studies are needed.
