Multiphase CTA vs. MRA collateral map for predicting functional outcomes after acute ischemic stroke.
Observational study in Neuroradiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo compare the prognostic abilities of multiphase CT angiography (mCTA) and multiphase MR angiography (MRA) collateral map in acute anterior circulation ischemic stroke.
methodsThis secondary analysis of a prospective observational study included data from participants with acute ischemic stroke due to steno-occlusion of the internal carotid artery and/or middle cerebral artery within 8 h of symptom onset between January 1, 2016, and March 31, 2021. The intermethod agreement of the collateral scores (CSs) from mCTA and the collateral perfusion scores (CPSs) from the MRA collateral map was analyzed. Multiple logistic regression analyses were conducted to determine the prognostic value of mCTA and MRA collateral maps.
results169 participants (106 men and 63 women, mean age 69 years ± 13) were included. The agreement between the CSs of mCTA and the CPSs of the MRA collateral map (weighted kappa = 0.44, 95% confidence interval [CI]: 0.37-0.52) of 168 participants was moderate. Younger age (Odds ratio [OR], 0.51; 95% CI, 0.34-0.76; p = 0.001), lower baseline NIHSS scores (OR, 0.89; 95% CI, 0.81-0.99; p = 0.024), CPS 4 (OR, 36.66; 95% CI, 1.79-750.29; p = 0.019) and CPS 5 (OR, 144.10; 95% CI, 1.11-18788.93; p = 0.046) on the MRA collateral map, and successful reperfusion (OR, 9.63; 95% CI, 3.00-30.94; p < 0.001) were independently associated with favorable functional outcomes.
conclusionsOnly the MRA collateral map demonstrated clinical prognostic value in acute anterior circulation ischemic stroke patients, demonstrating the superiority of the MRA collateral map over mCTA in collateral assessment.
