Normal values of the resistivity index of the pericallosal artery with and without compression of the anterior fontanelle.
Article in Pediatric radiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundResistivity index (RI) of the pericallosal artery as is commonly measured during head ultrasound (US) examination in neonates. Some studies have shown that RI measured with gentle compression of the fontanelle provides additional information in cases of neonatal brain anomalies.
objectiveThe purpose of this study was to establish normal RI values with and without compression in a large population of neonates with normal cranial ultrasound as a function of gestational age. MATERIALS AND
methodsThe authors of this retrospective study reviewed the RI of 323 infants with normal gray-scale cranial US and with a gestational age ranging 26-42 weeks. We conducted the exams both with and without compression of the anterior fontanelle and we studied changes in RI depending on gestational age, gender and type of delivery.
resultsInfants with a gestational age of more than 35 weeks tended to have a lower RI (P=0.011). The compression of the anterior fontanelle emphasized the change in RI with increasing gestational age, with higher gestational ages having a lower RI (P<0.001). The results concerning the percentage change between baseline RI and RI with compression showed that infants with higher gestational ages have a smaller percentage change in RI (P=0.002).
conclusionWe established the normal values for RI from 26 weeks to 42 weeks of gestation. The results of the study show the importance of taking the gestational age into consideration when evaluating the RI.
