Association between preoperative albumin and postoperative pneumonia in patients undergoing major non-cardiac surgery.
Article in Frontiers in nutrition, 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
Background: Postoperative pneumonia is a common and serious complication following non-cardiac surgery. However, the relationship between preoperative albumin levels and postoperative pneumonia remains unclear in major non-cardiac surgeries, and the cut-off value for predicting postoperative pneumonia has yet to be determined. Methods: Data from patients who underwent non-cardiac surgery between January 1, 2019, and December 31, 2022, were extracted from the institutional electronic medical records of Chongqing University Cancer Hospital. The primary exposure of interest was preoperative albumin levels, and the outcome was postoperative in-hospital pneumonia. Results: The results revealed a non-linear dose-response relationship between preoperative albumin levels and postoperative pneumonia. A 1 g/L increase in preoperative albumin levels was associated with a 4.4% reduction in adjusted odds ratio (aOR) of postoperative pneumonia (aOR: 0.956, 95% CI: 0.940-0.973, Conclusion: These findings suggest that preoperative albumin levels are significantly associated with the development of postoperative pneumonia in patients undergoing major non-cardiac surgery. A preoperative albumin level of <45.3 g/L may serve as a predictive marker for postoperative pneumonia.
