Baseline respiratory system compliance and its decline during general anesthesia for surgery: A retrospective observational study.
Observational study in Medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Maintaining respiratory system compliance (Crs) is a clue for lung recruitment strategies during surgery; however, patients' baseline Crs values have not been adequately addressed. We studied the association of low Crs at the induction of anesthesia (iCrs) with limited intraoperative respiratory management. We conducted a secondary analysis of retrospective study of consecutive surgical patients on ventilators between 2019 and 2020. The intra- and postoperative respiratory-related parameters were compared between the low iCrs group (<25% of the distribution) and others. Primary outcome was postoperative respiratory support related with iCrs and intraoperative Crs decline. Multivariate analysis and other root-cause analysis were performed to evaluate the relationships between low iCrs and outcomes. A total of 5568 patients were included and classified into either the low iCrs group (<43 mL/cmH2O, n = 1392) or the other group (n = 4176). The age was older and both the duration of surgery and the duration of anesthesia were shorter in the low iCrs group than in the other groups. Unexpectedly, the low iCrs group was associated with a smaller decrease in hourly changes in Crs (-1.4% [-11.3% to 11.2%] vs -13.0% [-21.3% to -5.3%], P < .001). Despite the smaller decrease in Crs, the low iCrs group showed a higher incidence of > 3 days of postoperative oxygen therapy (adjusted OR 1.60 (1.29-1.97), P < .001) and > 3 days of mechanical ventilation following surgery (adjusted OR, 1.55 (1.02-2.36), P = .039) than the other group. The significances in postoperative therapies were exaggerated in emergency surgery. The low iCrs patients showed a smaller decline in hourly changes in Crs and longer postoperative respiratory supports. Not only the decrease in Crs during surgery but also the initial Crs value warrant the intra- and postoperative respiratory management.
