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: Early recognition of postoperative neurologic deterioration in patients with traumatic brain injury (TBI) is essential but remains challenging, as clinical assessment may lack sensitivity and computed tomography (CT) imaging is not always immediately available. Transcranial Doppler (TCD) provides a noninvasive bedside method to detect early hemodynamic abnormalities, including impaired perfusion and increased vascular resistance. This case report highlights the role of TCD in recognizing early indicators of intracranial hypertension and prompting expedited CT evaluation. Case Description: A 20-year-old male presented with an acute decline in consciousness following a traffic accident. Initial CT imaging revealed an epidural hematoma, intraparenchymal hemorrhage, subarachnoid hemorrhage, cerebral edema, and a temporoparietal depressed skull fracture. The patient underwent decompressive craniectomy with hematoma evacuation. On postoperative day 1, neurologic status failed to improve, accompanied by anemia and elevated lactate. Bedside TCD demonstrated an increased pulsatility index (PI 1.49) and hypoechoic-hyperechoic changes in the lateral ventricle suggestive of new hemorrhage or cerebrospinal fluid accumulation. These findings prompted an urgent repeat CT scan, which confirmed new intracranial bleeding and the need for reoperation. Following re-craniotomy and further stabilization, repeat TCD showed a reduced PI (1.09) consistent with improved hemodynamics. Conclusion: When clinical assessment is limited and CT imaging is delayed, TCD serves as a valuable bedside tool for early recognition of rising intracranial pressure or new hemorrhage. Although not a substitute for CT, TCD functions as a diagnostic bridge that accelerates clinical decision-making in critical postoperative TBI care.
