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
Objectives: To investigate the effect of general anesthesia with spontaneous breathing laryngeal mask airway (LMA) intubation combined with a peripheral nerve block (PNB) in orthopedic surgery through a retrospective study. Methods: Data from 160 adult patients (American Society of Anesthesiologists grade 1-3) who underwent elective orthopedic surgery under general anesthesia with LMA intubation combined with PNB were retrospectively analyzed. All patients received ultrasound-guided PNB before general anesthesia. Among them, 78 patients were assigned to the spontaneous breathing group and 82 patients to the pressure-controlled ventilation group. The parameters compared included baseline characteristics, perioperative anesthetic drug dosages, anesthesia recovery time, adverse events during recovery, numerical rating scale score at 2 h postoperatively, postoperative pulmonary complications, hospitalization costs, and length of stay. Results: Both groups successfully completed the surgeries. Compared to the pressure-controlled ventilation group, the spontaneous breathing group exhibited significantly lower doses of fentanyl and rocuronium bromide ( Conclusion: General anesthesia with spontaneous breathing LMA intubation combined with PNB is safe and feasible for elective orthopedic surgeries in adults. This approach is beneficial in shortening the length of stay and reducing hospitalization costs.
