1 · What the graph read from 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.

2 · The registry

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

Objective: Aneurysmal subarachnoid hemorrhage (aSAH) is a severe stroke subtype often complicated by Delayed Cerebral Ischemia (DCI) and poor neurological outcomes. This study aims to develop novel predictive models for DCI and functional recovery following aSAH. Methods: A total of 195 cases with aSAH from Taian City Central Hospital, hospitalized between September 2019 and January 2023, were retrospectively analyzed. Patients were categorized into two groups: the DCI group and the non-DCI group. Additionally, patients were further categorized into the good outcome group and the poor outcome group based on modified Rankin scale scores assessed three months after discharge. We compared baseline characteristics among the different groups to identify key variables for subsequent multivariable logistic regression analysis. The nomogram was used to visualize the model. The Calibration Curve, Decision Curve Analysis (DCA) curve, and Receiver Operating Characteristic (ROC) curve were employed to evaluate the performance of these models. Results: In the model developed to predict DCI following aSAH, hypertension and Hunt-Hess grade emerged as independent risk factors ( Conclusions: We developed two nomograms to predict DCI and 3-month outcome after aSAH. Hypertension and Hunt-Hess grade predicted DCI, while age, Hunt-Hess grade, and ND predicted poor outcome. Both models showed stable discrimination on internal validation.
