1 · What the graph read from it

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.

2 · The registry

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

backgroundCarotid artery stenting (CAS) carries a risk of postoperative cerebral perfusion instability. This study evaluated a multidisciplinary staged blood pressure (BP) management protocol on cerebral hemodynamics and neurological outcomes.

methodsRetrospective analysis included 67 CAS patients: control group (n = 33) received conventional BP management; intervention group (n = 34) received staged BP protocol. Cerebral hemodynamics were assessed using transcranial Doppler (TCD), including middle cerebral artery mean flow velocity (MCA-Vm) and pulsatility index (PI). Baseline, 24 h, 48 h, and 72 h values were recorded. Preoperative MRI/MRA were reviewed for impaired perfusion surrogates. NIHSS and Barthel Index (BI) were evaluated.

resultsIntervention group showed more stable MCA-Vm and PI. MCA-Vm peaked at 24 h (72.3 ± 14.8 cm/s) then stabilized or decreased to 64.8 ± 10.4 cm/s at 72 h. PI decreased from 0.94 ± 0.18 to 0.86 ± 0.14 in the intervention group versus 0.92 ± 0.21 to 0.78 ± 0.19 in controls. Fewer BP target failures occurred (17.6% vs. 45.5%; P = 0.019), and rescue antihypertensive therapy was less frequent (17.6% vs. 42.4%; P = 0.034). NIHSS at discharge was lower (1 [IQR 1-3] vs. 3 [2-4]; P = 0.009) and BI at 30 days higher (91.5 ± 7.6 vs. 84.3 ± 10.4; P = 0.002). A small subset exhibited postoperative MCA-Vm reduction, indicating heterogeneous hemodynamic responses.

conclusionStaged postoperative BP management was associated with stable TCD-derived cerebral hemodynamics and improved neurological outcomes after CAS. Findings reflect surrogate hemodynamic changes rather than absolute cerebral blood flow, emphasizing individualized, monitored BP management.
