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

objectiveWe examined whether early diffusion-weighted magnetic resonance imaging (DW-MRI) abnormalities of the brain and variation of apparent diffusion coefficient (ADC) values can provide prognostic information on clinical outcome in children following cardiac arrest (CA).

designRetrospective study.

settingA 12-bed paediatric intensive care unit (PICU). PATIENTS: Children aged between 1 month and 18 years who had DW-MRI with ADC measurement within the first week following CA. Neurological outcomes were assessed using the Pediatric Cerebral Performance Category Scale (PCPC). Differences between the favourable (PCPC ≤3) and unfavourable (PCPC ≥4) groups were analysed with regard to clinical data, electrophysiological patterns as well as qualitative and quantitative DW-MRI abnormalities.

resultsTwenty children with a median age of 20 months (1.5-185) and a male/female sex ratio of 1.5 underwent DW-MRI after CA with a median delay of 3 days (1-7). Aetiologies of CA were (i) asphyxia (n = 10), (ii) haemodynamic (n = 5) or (iii) unknown (n = 5). With regard to DW-MRI findings, the unfavourable outcome group (n = 8) was associated with cerebral cortex (p = 0.02) and basal ganglia (p = 0.005) lesions, with a larger number of injured brain regions (p = 0.001) and a global decrease in measured ADC signal (p = 0.008). Normal DW-MRI (n = 5) was exclusively associated with the favourable outcome group (n = 12).

conclusionQualitative, topographic and quantitative analysis of early DW-MRI with ADC measurement in children following CA may provide valuable prognostic information on neurological outcomes.
