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
We assessed the technical utility and preliminary outcomes of endoscopic hematoma evacuation via the high parietal approach for thalamic hemorrhage with intraventricular extension (intraventricular hemorrhage) by retrospectively reviewing 270 patients treated between April 1, 2006, and July 31, 2024. Prior to 2017, the primary treatment was external ventricular drainage, and in selected patients with thick intraventricular hematoma, an anterior endoscopic approach was used primarily for intraventricular hemorrhage removal. Since April 2017, the high parietal approach technique has been used for the simultaneous removal of both thalamic hematoma and intraventricular hemorrhage in 21 patients. The high parietal approach group showed a median hematoma evacuation rate of 92.2% and, compared with the external ventricular drainage-only group, a significantly shorter duration of ventricular drainage and a lower incidence of tracheostomy. No cases of surgical site infection or meningitis occurred in the high parietal approach group. Complications included 1 death due to postoperative rebleeding and another due to worsening pneumonia and heart failure. Secondary hydrocephalus requiring shunt placement was observed only in the external ventricular drainage group. Although not statistically significant, the high parietal approach group showed a higher rate of early resumption of oral intake. These findings suggest that endoscopic evacuation via the high parietal approach is a minimally invasive technique that achieves high hematoma removal rates, facilitates early postoperative recovery, and may reduce complications such as prolonged drainage, tracheostomy, and hydrocephalus in selected patients with large thalamic hemorrhage and intraventricular hemorrhage.
