A prospective cross-sectional study of fetal middle cerebral artery peak systolic velocity in a normal obstetric population attending an Indian Medical College.
Article in Japanese journal of radiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeFetal middle cerebral artery peak systolic velocity (MCA-PSV) is now an established method of noninvasive diagnosis of moderate to severe fetal anemia of different origins. This being a population-based parameter, it may have different values in individuals from different locations. A standard local reference range of normal individuals specific to each geographic locality is therefore needed. MATERIALS AND
methodsFetal MCA-PSV was measured in 1,015 healthy pregnant women attending the antenatal ultrasound clinic at least once between 12 and 40 weeks of gestation (35 patients per week of gestation). Statistical analysis was done using the SPSS 12 software.
resultsA positive correlation between MCA-PSV and gestational age was found. MCA-PSV was seen to increase with advancing gestational age. The Tukey-Kramer multiple comparisons test showed a normal distribution that was highly significant (p < 0.01). The multiples of median values of fetal MCA-PSV to label a fetus as severely anemic were consistently and significantly lower than internationally accepted values.
conclusionsA normal reference range of fetal MCA-PSV for local use was thus scientifically and successfully constructed. Significant differences between local values and internationally accepted value were found.
