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
Intracerebral hematomas (ICH) with intraventricular hemorrhage (IVH) are associated with high morbidity. Catheter-based thrombolysis with recombinant tissue plasminogen activator (rtPA) allows a faster hematoma resolution compared to conservative treatment. However, simultaneous thrombolysis of ICH and IVH is not achievable because the ependyma hinders ICH-lysis if rtPA is given into the ventricles and inversely. We evaluated if the thrombolysis efficacy is enhanced by placing an intrahematomal catheter reaching the ventricle. Patients with ICH plus IVH treated with catheter-based thrombolysis were retrospectively analyzed. Group 1 included patients with an intrahematomal catheter reaching the ventricles and group 2 patients with a catheter placed exclusively in the ICH. The relative hematoma volume reduction (RVR) of ICH and IVH within 3 days was calculated. Furthermore, the patients' outcome, the hydrocephalus incidence, and the infection rate were evaluated. A total of 74 patients were analyzed, of whom 49% had a catheter reaching the ventricle. The mean ICH-RVR (68% vs. 58%, p = 0.0001) and IVH-RVR were significantly higher in group 1 compared to group 2. In group 1, infections occurred more often compared to group 2 (31% vs. 6%, p = 0.005). There was no difference in outcome and in hydrocephalus incidence between both groups. The catheter reaching the ventricles allows simultaneous and more effective thrombolysis of ICH and IVH. We assume that the fibrinolytic property of cerebrospinal fluid itself and a washout effect contribute to these findings. In patients with ICH plus IVH, catheter positioning through the hematoma into the ventricle, and subsequent fibrinolytic therapy should be considered.
