Ultrasound guided individualized PEEP reduces postoperative atelectasis in elderly patients undergoing laparoscopic radical rectal cancer surgery.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Older patients undergoing laparoscopic radical rectal cancer surgery under general anesthesia with mechanical ventilation face an increased risk of postoperative pulmonary atelectasis due to the Trendelenburg position and pneumoperitoneum. This study aims to assess whether lung ultrasound-guided individualized positive end-expiratory pressure(PEEP) ventilation can reduce postoperative atelectasis in older patients. Forty patients aged > 65 years scheduled for elective laparoscopic radical rectal cancer surgery were randomly assigned to two groups: the ultrasound-guided group (Group P) received individualized PEEP titrated by lung ultrasound, and the control group (Group C) maintained a fixed PEEP of 5 cmH
