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
Determine whether APOE gene polymorphism is associated with hypoperfusion intensity ratio (HIR) in acute ischemic stroke (AIS) patients with large vessel occlusion (LVO). Continuously reviewed hospitalized LVO-AIS patients. According to whether the patients carried APOE allele ε 4, they were divided into 2 groups: ε4 carriers and non-ε4 carriers. CTP assessed HIR and infarct core (IC) volume. Good collaterals were defined as HIR < 0.4 and poor collaterals were defined as HIR ≥ 0.4. The patients were divided into two groups based on their HIR value: the HIR < 0.4 group and the HIR ≥ 0.4 group. IC volume was a rCBF < 40% volume. NIHSS at admission assessed stroke severity. A total of 101 patients with LVO-AIS were enrolled, including 82 patients with HIR < 0.4 and 19 patients with HIR ≥ 0.4. Among the patients with HIR < 0.4, 10 were ε4 carriers (12.20%), while among those with HIR ≥ 0.4, 8 were ε4 carriers (42.11%). The proportion of ε4 carriers was significantly higher in the HIR ≥ 0.4 patients group (P = 0.006). In all enrolled patients, there were 83 non-ε4 carriers and 18 ε4 carriers. The IC volume in ε4 carriers was significantly higher than that in non-ε4 carriers (P = 0.003). The NIHSS score in ε4 carriers was significantly higher than that in non-ε4 carriers (P = 0.004). Binary logistic regression showed that APOE ε4 was an independent risk factor for poor collaterals (OR = 6.00, 95%CI: 1.80, 20.02, P = 0.004). Multiple linear regression showed HIR had a significant positive effect on IC volume (B = 167.70, P < 0.001) and NIHSS score (B = 8.53, P = 0.014). APOE ε4 is an independent risk factor for poor collaterals.
