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: Patients with chronic obstructive pulmonary disease (COPD) experience an increased risk of perioperative pulmonary complications. The aim of this study was to evaluate the effect of albuterol spray on hypoxia and bronchospasm in patients with COPD under general anesthesia. Methods: This single-center, double-blind, parallel-group, randomized clinical trial was performed on 120 smoking patients with COPD who were referred to 5 Azar Educational Hospital in Gorgan, Northern Iran, in 2021. Twenty minutes before general anesthesia and also after completion of surgery and before extubation, 60 patients in the intervention group were inhaled with 2 puffs of albuterol spray. In the control group, patients were inhaled with 2 puffs of placebo spray. In perioperative period, the occurrence of wheezing, bronchospasm, coughing, hemodynamic changes, postoperative shivering, dyspnea, and nausea and vomiting were evaluated in all patients. The Consolidated Standards of Reporting Trials (CONSORT) checklist was used to report important aspects of this study. Results: The mean age of the patients was 52.34 ±8.95 years, and 115 (95.8%) of them were males while the rest were females. The difference between systolic blood pressure before induction of anesthesia (after administration of albuterol spray) between the group receiving albuterol spray and the group not receiving it was statistically significant (p=0.04). Also, the difference between the mean arterial oxygen saturation before tracheal extubation (after re-administration of albuterol spray) between the albuterol spray group and the non-albuterol group was statistically significant (p = 0.03). Wheezing and recurrent cough after induction of anesthesia and after extubation (after albuterol spray administration) was lower in the albuterol group than in the control group (p<0.05). No significant side effects were detected in the albuterol-treated group. Conclusion: According to the results of this study, it seems that the prophylactic use of albuterol spray is useful in reducing the incidence of wheezing and recurrent cough before induction of anesthesia in COPD patients with smoking.
