Diaphragm Dysfunction After Cardiac Surgery.
Article in Brazilian journal of cardiovascular surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionDiaphragm elevation is commonly seen after cardiac surgery, mostly due to phrenic nerve injury. However, only historical data is available on the incidence of diaphragm elevation and its consequences during recovery.
objectiveWe aim to provide contemporary insights into the incidence of diaphragm dysfunction in patients undergoing cardiac surgery and its effect on postoperative outcomes.
methodsRecords of all patients undergoing cardiac surgery through sternotomy between 2015 and 2016 at the Radboud University MedicalCentre were retrospectively reviewed. Diaphragm position and elevation were evaluated on available chest radiography. Right-sided diaphragm elevation was defined as the right diaphragm being > 3.0 cm above the left diaphragm; left-sided diaphragm elevation was defined as < 0.5 cm below or above the level of the right diaphragm.
resultsA total of 1510 patients have undergone cardiac surgery through sternotomy during the study period, of which 1316 patients were included in the final analysis. Of these 1316 patients, 13% (n = 179) had pre-existing diaphragm elevation, 27% (n = 351) had a new diaphragm elevation postoperative-y, and 60% (n = 786) had no diaphragm elevation. No statistically significant differences were found between the groups in the occurrence of postoperative (pulmonary) complications or mortality. Of patients who developed new diaphragm elevation postoperatively, 65% recovered in the follow-up period.
conclusionNew postoperative diaphragm elevation occurs in 27% of patients undergoing cardiac surgery. However, new postoperative diaphragm elevation is not associated with a higher incidence of postoperative complications and spontaneous recovery is seen in most patients.
