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

introductionEvidence regarding the prognostic significance of thrombocytopenia in spontaneous intracerebral haemorrhage (ICH) remains limited and inconsistent. We investigated its associations with haematoma expansion (HE), functional outcomes and mortality. PATIENTS AND

methodsWe retrospectively analysed prospectively collected data from consecutive patients with spontaneous ICH in a single-centre registry between August 2022 and March 2025. Thrombocytopenia was defined as an admission platelet count <150 × 109/L. HE was defined as a haematoma-volume increase >6 mL or >33% on follow-up noncontrast computed tomography. Poor functional outcome was defined as a modified Rankin Scale (mRS) score of 3-6 at 3 months. Associations were assessed using multivariable logistic regression, restricted cubic splines, ordinal regression and sensitivity analyses.

resultsAmong 496 patients, 106 (21.4%) had thrombocytopenia; 368 were included in the HE analysis. After adjustment, thrombocytopenia showed no statistically significant association with HE (adjusted OR 0.97, 95% CI, 0.52-1.76; P = .920), 3-month poor functional outcome (adjusted OR 0.88, 95% CI, 0.46-1.66; P = .693), or 3-month mortality (adjusted OR 1.43, 95% CI, 0.70-2.89; P = .324). Restricted cubic spline analysis showed no statistically significant overall association and the test for nonlinearity was not statistically significant. Findings were similar across platelet-count categories, continuous haematoma-volume changes, ordinal mRS analyses and sensitivity analyses addressing imaging timing, early surgery, acute treatments and prior anticoagulant use. DISCUSSION: Admission thrombocytopenia showed no statistically significant association with HE, poor functional outcome, or mortality after ICH. Because few patients had platelet counts <100 × 109/L, these findings mainly apply to mild thrombocytopenia.
