Early vs Delayed Antihypertensive Treatment in Acute Single Subcortical Infarction: A Secondary Analysis of the CATIS-2 Randomized Clinical Trial.
Trial report in JAMA network open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03479554 (China Antihypertensive Trial in Acute Ischemic Stroke II), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled 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.

Abstract
Importance: The China Antihypertensive Trial in Acute Ischemic Stroke II (CATIS-2) suggests that early antihypertensive treatment did not reduce the risk of dependency or death in acute ischemic stroke (AIS), compared with delayed treatment. Single subcortical infarction (SSI) is an important stroke subtype, and the association of antihypertensive timing with clinical outcomes is unclear. Objective: To investigate the association of early vs delayed antihypertensive treatment with clinical outcomes in patients with SSI, stratified by the presence of parent artery disease (PAD) stenosis. Design, Setting, and Participants: This secondary analysis of the CATIS-2 randomized clinical trial included 106 hospitals in China between June 2018 and July 2022. In CATIS-2, patients with AIS within 24 to 48 hours of symptoms onset and elevated systolic blood pressure were eligible. Patients with SSI detected in diffusion-weighted imaging were included in the current post hoc subgroup analysis. Patients were grouped into (1) SSI with PAD stenosis and (2) SSI without PAD stenosis. Statistical analysis was performed from July 2023 to May 2024. Exposures: Early (immediate) vs delayed (starting on day 8) antihypertensive therapy. Main Outcome and Measure: Primary outcome was the combination of functional dependency or death (modified Rankin Scale score ≥3) at 90 days. Results: Among 997 patients with SSI in CATIS-2 (mean [SD] age, 62.4 [9.8] years; 612 [61.4%] men), 116 (11.6%) had SSI with PAD and 881 (88.4%) had SSI without PAD. There was no significant difference in the primary outcome between early and delayed antihypertensive treatment groups among all patients with SSI (8.8% vs 7.1%; OR, 1.25 [95% CI, 0.79-1.99]; P = .34). Among patients with SSI with PAD, early antihypertensive treatment was associated with increased risk of the primary outcome compared with delayed treatment (23.4% vs 7.7%; OR, 3.67 [95% CI, 1.14-11.86]; P = .03); this finding was not observed in patients with SSI without PAD (6.6% vs 7.1%; OR, 0.93 [95% CI, 0.55-1.57]; P = .77). Significant interaction with treatment and presence of PAD stenosis was detected for the primary outcome (P for interaction = .04). Conclusions and Relevance: In this secondary analysis of a randomized clinical trial, early antihypertensive treatment was associated with an increased risk of functional dependency or death at 90 days among patients with SSI and coexisting PAD stenosis, compared with delayed antihypertensive treatment. Further studies are warranted for individualized BP management in patients with SSI by the presence of PAD. Trial Registration: ClinicalTrials.gov Identifier: NCT03479554.
