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

backgroundPassive smoking is linked to increased respiratory adverse events (AEs) during general anesthesia (GA). This study aims to assess whether females exposed to passive tobacco smoke undergoing GA, experience a higher incidence of perioperative respiratory AEs.

methodsThis single-center prospective cohort study was conducted from July 2021 to July 2022, at a University Hospital. After approval from the ethical review committee, 150 female patients receiving GA for elective surgeries requiring endotracheal intubation were included and classified into Passive Smoking Exposure (PSE) and Non-Passive Smoking Exposure (NPSE) groups. Data on respiratory adverse events (AEs) including laryngospasm, bronchospasm, breath holding, desaturation, hypersecretion, coughing, wheezing, and stridor during the perioperative period was collected using a proforma. Statistical analysis was performed using RStudio with Chi-square, Fisher's exact test, and Mann-Whitney U test to determine significance.

resultsAmong 150 female participants, 75 were included in the PSE and 75 in the NPSE groups. The PSE group had an overall statistically significant incidence of respiratory AEs compared to the NPSE group (69.3 vs. 16.0%, p < 0.001). Hypersecretion (50.7% vs. 4%) and desaturation (38.7% vs. 6.7%) intraoperatively and desaturation (14.7% vs. 1.3%) and cough (10.7% vs. 0% ) in the post-anesthesia care unit (PACU) were significantly more common in the PSE group (p < 0.001). At 12 h postoperatively, 56% of the PSE group had respiratory issues versus 32% in the NPSE group (p < 0.05).

conclusionPassive smokers had a significantly higher incidence of perioperative respiratory AEs with GA, necessitating the need for preoperative strategies to address passive smoke exposure.
