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
BackgroundEndovascular therapy (EVT) improves functional outcomes and reduces mortality in acute ischemic stroke (AIS) due to basilar artery occlusion (BAO). However, data on hemorrhagic complications and nonneurologic adverse events remain limited. We conducted a systematic review and meta-analysis to assess these outcomes in randomized controlled trials (RCTs) comparing EVT versus best medical management (BMM).MethodsWe searched PubMed, Cochrane Library, and Embase in December 2024 for RCTs comparing EVT and BMM (PROSPERO registry CRD42024617681). Outcomes included any parenchymal hematoma (PH), PH type 1 and 2, subarachnoid hemorrhage (SAH), systemic/extracranial hemorrhage, pneumonia, and heart failure. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using a random-effects model.ResultsFour RCTs, 988 patients (556 EVT, 432 BMM), were included. EVT increased the risk of SAH (RR 5.14; 95% CI [1.35-19.56]; I² = 0.0%) and PH type 2 (RR 5.53; 95% CI [1.47-20.84]; I² = 0.0%) compared to BMM. No significant differences were observed for any PH (RR 1.91; 95% CI [0.92-3.97]; I² = 0.0%), PH type 1 (RR 0.71; 95% CI [0.22-2.29]; I² = 3.4%), systemic/extracranial hemorrhage (RR 1.06; 95% CI [0.71-1.60]; I² = 12.2%), pneumonia (RR 1.00; 95% CI [0.83-1.21]; I² = 0.0%), or heart failure (RR 2.00; 95% CI [0.34-11.92]; I² = 55.4%).ConclusionIn patients with BAO AIS, EVT is associated with an increased risk of SAH and PH type 2 compared with BMM. There was no significant difference in any PH, PH type 1, systemic/extracranial hemorrhage, pneumonia, and heart failure between groups.
