Feasibility and safety of passive orthostatic positioning in mechanically ventilated ICU patients: A prospective observational study.

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
Early mobilization strategies are essential for preventing intensive care unit (ICU) - acquired complications. However, the feasibility of passive orthostatism in mechanically ventilated patients remains underexplored. This study evaluates the safety and acute physiological effects of passive orthostatic positioning using an orthostatic board in critically ill patients undergoing invasive mechanical ventilation. A single-group exploratory study was conducted in an ICU setting with 13 adult patients. Each patient underwent a single passive orthostatic session using a motorized orthostatic board. Physiological (hemodynamics and ventilatory mechanics) and neurological (glasgow coma scale [GCS]) parameters were measured at 3 time points: pre-intervention, immediately post-intervention, and 20 minutes after upright positioning. A repeated-measures linear mixed model with Kenward-Roger correction and permutation testing was used for analysis. The study included 13 ICU patients (mean age 60.92 ± 14.53 years; 53.8% male). Significant improvements were observed in the tidal volume (VT), driving pressure, and GCS scores across the 3 time points. Driving pressure decreased markedly (P <.001), whereas GCS score increased significantly (P <.001). The heart rate also showed a significant increase at 20 minutes (P = .019). No significant changes were noted in mean arterial pressure, SpO2, or respiratory rate. No adverse events occurred during the study. Passive orthostatism using an orthostatic board is a safe and feasible early mobilization strategy for mechanically ventilated ICU patients. This resulted in improved ventilatory mechanics and level of consciousness, without hemodynamic instability or complications. These findings support further investigations of orthostatic positioning as a complementary tool for ICU rehabilitation.
