Mitochondrial DNA in plasma and long-term physical recovery of critically ill patients: an observational study.
Article in Intensive care medicine experimental, 2024. 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
backgroundPost-intensive care syndrome (PICS) poses a notable public health concern, with survivors of critical illness experiencing long-term physical, psychological, and cognitive challenges. Mitochondrial dysfunction has gained attention for its potential involvement in PICS. However, the long-term impact of mitochondrial status on patient recovery remains uncertain. A single-centre retrospective analysis was conducted in Leeuwarden, the Netherlands, between May and November 2019, within a mixed ICU survivor cohort. Patients were assessed for mitochondrial markers (mtDNA damage represented by the presence of mtDNA fragmentation and mitochondrial DNA levels evaluated by the ratio of mtDNA and nuclear DNA), clinical factors, and long-term outcomes measured by the physical functioning (PF) domain of health-related quality of life.
resultsA total of 43 patients were included in this study divided into recovery and non-recovery groups based on age-adjusted PF scores at 12 months post-ICU. Nineteen patients scored below these thresholds. No significant differences in mitochondrial markers between groups were identified. Furthermore, no significant correlations were found between mtDNA levels and mtDNA damage at baseline and 12 months with PF scores. However, mtDNA levels decreased over time in the recovery (p-value < < 0.01) and non-recovery groups (p-value < 0.01).
conclusionNo significant correlation was found between mitochondrial markers and physical functioning scores. This study underscores the multifactorial nature of PICS and the need for a comprehensive understanding of its metabolic and cellular components. While mitochondrial markers may play a role in PICS, they operate within a framework influenced by various factors. This exploratory study serves as a foundation for future investigations aimed at developing targeted interventions to enhance the quality of life for ICU survivors grappling with PICS.
