Autoantibodies targeting G protein-coupled receptors and clinical outcome after ischemic stroke (PROSCIS-B).
Observational study in Journal of neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01363856 (Center for Stroke Research Berlin), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundG protein-coupled receptor (GPCR) directed regulatory autoantibodies (RABs) have previously been linked to poor functional outcome after ischemic stroke. We investigated the impact of anti-α1/α2/β1/β2 receptor, endothelin B receptor, angiotensin II receptor type 2, and CXCR3 receptor directed RABs on functional outcome and recurrent events after ischemic stroke.
methodsData were derived from the Prospective Cohort with Incident Stroke Berlin (PROSCIS-B; NCT01363856). RABs were measured by ELISA (CellTrend) from sera collected within seven days of first-ever stroke. High RAB levels (quartile [Q]4 vs. Q1-3) and low levels (Q1 vs. Q2-4) were compared to reference groups. Quartile subgroups were characterized at baseline. Functional outcome, measured by the Modified Rankin Scale (mRS) at one year, was evaluated with ordinal logistic regression. Cox proportional hazard models were used to assess risk for a combined endpoint (stroke, myocardial infarction, death) over three years.
results562 patients were included (mean age 67 (SD= 13); 38% female). All RABs showed more large artery atherosclerosis (LAA) stroke in Q1, while cardioembolic strokes (CE) were more frequent in Q4. Worse functional outcome at 12 months was associated with high levels (Q4) of alpha2-antibodies (abs) (OR=1.49; 95%CI=1.02-2.18) and ETB-abs (OR=1.49; 95%CI=1.02-2.18) vs. Q1-Q3. Recurrent cardiovascular risk over three years was higher with low levels (Q1) of AT2-abs (HR=1.86; 95%CI=1.22-2.86), alpha2-abs (HR=1.77; 95%CI=1.15-2.72), and beta1-abs (HR=1.58; 95%CI=1.03-2.44) vs. Q2-Q4.
conclusionDifferential associations of low vs. high levels of several RABs with stroke etiology, functional outcome, and recurrent vascular risk suggest potential roles in stroke pathophysiology.
