1 · What the graph read from itWhat 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 registryThe 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.

6 · The paper itselfAbstract
backgroundAntiphospholipid antibodies (aPL) are associated with an increased risk of thrombosis. However, individual studies have reported conflicting findings regarding the prevalence of aPL in patients with ischemic stroke and their association with first or recurrent events.
methodsSystematic searches of PubMed and Embase through May 13, 2025 were conducted to identify case-control, cohort, or cross-sectional studies investigating 3 questions related to aPL seropositivity (defined as positivity for either immunoglobulin G/immunoglobulin M anticardiolipin antibody, immunoglobulin G/immunoglobulin M anti-β2 glycoprotein I antibody, or a lupus anticoagulant): (1) the prevalence of aPL seropositivity among individuals with ischemic stroke; (2) the association between aPL seropositivity and the risk of first ischemic stroke; and (3) the association between aPL seropositivity and the risk of recurrent ischemic stroke. Random-effects models with inverse weighting were used to calculate pooled prevalences and odds ratios (OR) with 95% CIs. Risk of bias was assessed using the ROBINS-I tool.
resultsA total of 52 studies were included (40 case-control, 12 cohort). The pooled prevalence of seropositivity for any aPL among patients with ischemic stroke (51 studies, 9438 patients) was 19.1% (95% CI, 15.4%-23.0%;
conclusionsSeropositivity for any aPL was present in nearly 1-in-5 patients with ischemic stroke and was associated with increased odds of ischemic stroke at presentation.
