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
objectiveThe surgical method for treating spontaneous intracranial hemorrhage (ICH) is not well established despite ICH's high prevalence and poor prognosis. Minimally invasive surgery has recently received attention; however, literature on this method is scarce. In particular, the appropriate location of the catheter in the hematoma has not been described. We examined whether the catheter position affects the hematoma reduction in a hematoma ＞50 cc.
methodsWe investigated the prognoses of 36 patients with ICH who underwent stereotactic aspiration and hematoma drainage using urokinase from January 2010 to December 2018 and the hematoma reduction rates according to the tube position. Two methods evaluated the position of the catheter. In the first method, the hematoma was an imaginary sphere. The center point was set as the operation target. We evaluated the catheter position by determining whether it was in the deep part or the outer part of the half point from that location to the hematoma margin. In the second method, we evaluated whether the catheter was located 1 cm inside the hematoma margin.
resultsIn both the first and second evaluations, there were no differences in age, midline shift, intraventricular hemorrhage status, hematoma volume on admission, Glasgow Coma Scale score on admission, time to operation after symptom onset, and systolic blood pressure. The rates of decrease in bleeding and the prognoses were also not significantly different.
conclusionsIf the catheter is in the hematoma, the rate of hematoma reduction at any position is similar.
