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
Background and purpose: This study aimed to investigate the independent and joint effects of two novel lipid-derived biomarkers-Remnant cholesterol (RC) and Cholesterol, high-density lipoprotein, and glucose (CHG) index-with hemorrhagic transformation (HT) and poor prognosis in patients with acute ischemic stroke (AIS) after intravenous thrombolysis (IVT). Methods: In this dual-center retrospective cohort study, 4403 AIS patients undergoing IVT were analyzed. RC and the CHG index were calculated from routine baseline biochemical measurements. The primary outcome was HT, and the secondary outcome was poor prognosis at 90 days (modified Rankin Scale [mRS] score > 2). Multivariable logistic regression and restricted cubic spline (RCS) models were used to assess linear and non-linear associations. Subgroup and receiver operating characteristic (ROC) analyses were conducted to evaluate robustness and discriminative ability. Mediation analysis explored the potential mediating role of the systemic immune-inflammation index (SII). Results: Patients with HT or a poor prognosis had lower RC and CHG levels. Multivariate logistic regression analysis revealed that both RC and CHG were negatively associated with the risk of HT and with a poor prognosis. The joint effects showed that patients with higher levels of RC and CHG had a significantly lower risk of HT (OR = 0.18, 95% CI: 0.12-0.25) and poor prognosis (OR = 0.40, 95% CI: 0.32-0.49). Subgroup analyses confirmed the consistency of these negative associations across age, sex, baseline NIHSS, and vascular comorbidities. The RCS models showed a non-linear association between RC and poor prognosis ( Conclusion: High RC and CHG levels were associated with a lower risk of HT and poor prognosis in AIS patients undergoing IVT. Integrating these biomarkers enhances predictive performance, supporting their potential utility in pre-thrombolysis risk stratification and personalized treatment decision-making.
