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.
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
purposeMorphological MRI can describe the brain structures and bleeding location but cannot describe the hydrocephalus' mechanisms in intraventricular hemorrhage (HIVH) in preterms. We have shown previously that phase-contrast MRI (PCMRI) can be used to quantify cerebral blood and CSF dynamics in newborns. The objective of the present study was to evaluate the impact of HIVH on CSF oscillations and blood flows in premature infants with hydrocephalus.
methodsFifteen preterm infants with HVIH underwent morphological MRI and PCMRI between 3 weeks and 6 years after birth. We used PCMRI to quantify CSF flows in the aqueduct of Sylvius and in the spinal canal.
resultsDifferent morphological types of hydrocephalus were observed. We found communicating and obstructive hydrocephalus. We found different hydrodynamic behaviors at intraventricular and subarachnoid levels. The morphological analysis of the spinal canal did not systematically correspond to the PCMRI results. At the aqueduct, the results were concordant in three cases only.
conclusionsPCMRI can quantify CSF and blood flows in newborns, reveal abnormally low or high CSF flows when a morphologic analysis cannot, and provide information that complements the morphological analysis and might be useful for understanding the physiopathology of the condition.
