Influence of age on outcomes in prolonged weaning from mechanical ventilation.
Article in BMJ open respiratory research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundOlder age has been identified in many studies as a predictor of poor outcomes in intensive care, including weaning failure. Age is a risk factor for prolonged weaning, resulting in an increased number of geriatric patients being referred to specialist weaning centres. The aim of our analysis was to investigate weaning outcomes in different age groups.
methodsWe analysed patients in prolonged weaning at Thoraxklinik Heidelberg from 1 December 2008 to 31 December 2023. We classified three groups: ≤64, 65-79 and ≥80 years of age. The patients' characteristics and weaning success, as well as weaning failure (continued invasive mechanical ventilation (IMV) and death), were analysed using group comparisons and logistic regression analyses.
resultsDuring the study period, 915 patients (64.9±13.7 years, 39.3% female) underwent prolonged weaning. 73.3% were successfully weaned, 20.2% were discharged with IMV and 6.6% died. 40.5% of the patients were ≤64 years, 49.7% were 65-79 years and 9.7% were ≥80 years old. There was a significant difference in weaning success: in the group ≤64 years the success rate was 79.0%, 65-79 years 70.3% and ≥80 years 64.0%, p=0002. The patients' characteristics differ in the age groups, with more postoperative patients, delirium and cardiovascular comorbidities and less neuromuscular disease and malignancy in ≥80 years old patients.
conclusions64% of carefully selected patients ≥80 years of age could be successfully weaned in a specialised centre instead of being discharged from a general intensive care unit with continuing IMV in an outpatient intensive care setting.
