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
purposeThe lenticulostriate arteries (LSA) and other perforators may play a role for collateral supply in cases with ischemia due to stenosis or occlusions of the middle cerebral artery (MCA). Purpose of this case series was to evaluate the potential of time-resolved 3D rotational angiography data sets (4D DSA) for detailed visualization of anatomic variants of LSA feeders and for display of local collaterals involving the LSA in cases with chronic MCA obstruction.
methodsMultiplanar and volume rendering reconstructions of 4D DSA data were computed in addition to standard postprocessing in 24 patients who had indications for 3D rotational angiography (3DRA) of the internal carotid artery (ICA) without pathologies of the ICA, middle cerebral artery (MCA) and anterior cerebral artery (ACA) main stems (n = 18) or with stenosis or chronic occlusion of the MCA (n = 6). For acquisition of 3DRA, we used a modified digital subtraction angiography (DSA) image acquisition protocol with an extended rotation angle of 260° and a prolonged scan time of 12 s on a Siemens Axiom Artis Zee biplane neuroangiography equipment. The 4D reconstructions of existing 3DRA data were computed on a dedicated workstation. Origin and course of LSA and other perforators were analyzed according to coronal multiplanar reconstructions (MPRs) with slice thicknesses between 6 and 28 mm.
resultsIn all cases 4D reconstructions of the LSA were technically feasible and evaluable. As expected, origin and course of LSA showed a wide range of variations: The most common pattern was a common trunk dividing into multiple ascending branches originating from the proximal M1 (n = 5) or the proximal A1 segment (n = 4). Alternatively, 8 patients showed several individual branches that directly originated from the proximal M1 segment of the MCA and occasionally from the A1 segment of the ACA. In patients with M1 stenosis or occlusion, 4 out of 6 cases had local collaterals with involvement of proximal LSA trunks and a network parallel to the obstructed vessel segment. The 4D reconstructions were found to be equivalent (n = 16) or superior to 3D reconstructions (n = 8).
conclusionThe 4D DSA reconstructions provide a reliable display of normal LSA variants and connections to local collateral networks in cases with chronic MCA obstruction. The possibility to select a correct angiographic phase is advantageous compared to 3D DSA.
