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
BackgroundRapid thrombectomy initiation is critical for improving outcomes in acute ischemic stroke (AIS) due to large vessel occlusion (LVO). Direct transport to an angiography suite (DTAS), bypassing standard Emergency Department CT imaging, Direct to ED CT (DTCT), reduces door-to-puncture times. This study compares standard DTCT and expedited DTAS workflows using a hybrid multidetector CT (MDCT)-angiography suite.Materials and methodsThis single-center, prospective, blinded analysis study simulated AIS care using a medical mannequin. Twelve simulations were conducted (six per protocol): (a) Standard DTCT and (b) Direct DTAS. Simulations included ED arrival, triage, clinical assessment, imaging, and groin puncture. All mock patients had LVO and were thrombectomy candidates (S-LAMS ≥ 4) with contraindications to lysis. Time metrics were measured and compared.ResultsMean door-to-puncture time was significantly shorter in the DTAS group (DTCT: 39.83 [4.36] min vs DTAS: 22.17 [2.4] min (
