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.

Abstract

objectiveWe tested the hypothesis that the maximally treated intracerebral hemorrhage (max-ICH) score is superior to the ICH score for characterizing mortality and functional outcome prognosis in patients with ICH, particularly those who receive maximal treatment.

methodsPatients presenting with spontaneous ICH were enrolled in a prospective observational study that collected demographic and clinical data. Mortality and functional outcomes were measured by using the modified Rankin Scale at 3 months. The ICH score and max-ICH score incorporate measures of symptom severity, age, hematoma volume, hematoma location, and intraventricular hemorrhage, with the max-ICH score also including a term for oral anticoagulation and having 16 score categories vs 11 for the ICH score. We compared the area under the receiver operating characteristic curve (AUC) for the ICH score and max-ICH score for both mortality and poor functional outcome, defined as modified Rankin Scale scores 4-6.

resultsWe analyzed outcomes for 372 patients, including 71 patients (19%) in whom care limitation/withdrawal of life support was instituted. Both the ICH score and max-ICH score showed good prognostic performance for 3-month mortality and poor functional outcomes in the full group as well as the subgroup with maximal treatment (i.e., no care limitations; AUC range 0.80-0.86), with no significant difference in AUC between the scores for either endpoint in either group.

conclusionsExternal validation with direct comparison of the ICH score and max-ICH score shows that their prognostic performance is not meaningfully different. Alternatives to simple scores are likely needed to improve prognostic estimates for patient care decisions.
