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

Sex dimorphism has been demonstrated after experimental intracerebral hemorrhage (ICH). Decreased mortality and improved neurobehavioral outcomes occur in female compared to male mice after intrastriatal autologous blood or collagenase injection. Sex-specific differences in post-ICH gene and protein expression may provide mechanistic insight into this phenomenon. Ten- to 12-week-old C57BL/6 male (M) and female in high estrous state (HE-F) underwent left intrastriatal collagenase injection. We assessed neurobehavioral outcomes over the first 30 days, hematoma volume and cerebral edema evolution over the first 24 h, and transcriptomic gene and protein expression at pre-selected time points during the acute phase of injury. Genome-wide expression profiling was performed with Affymetrix GeneChip Mouse Genome 2.0 Probes, and proteomics analyses were performed using mass spectroscopy. Sex does not affect hemorrhage evolution, but female sex is associated with improved neurobehavioral recovery after ICH. A total of 7037 probes qualified for our filtering criteria, representing 5382 mapped genes and 256 unmapped genes. Female-unique pathways involved cell development, growth, and proliferation, while male-unique pathways involved molecular degradation. At 6 and 24 h post-ICH, differential expression was observed in 850 proteins vs baseline in males, 608 proteins vs baseline in females, and 1 protein in females vs males. Female sex is associated with improved neurobehavioral recovery, and differential gene and protein expression after intrastriatal collagenase injection.
