Correlation between surfactant protein B mRNA expression and neonatal respiratory distress syndrome.

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
The aim of this study was to investigate whether surfactant-associated protein B (SP-B) mRNA deficiency is involved in the pathogenesis of neonatal respiratory distress syndrome (RDS). A total of 60 unrelated neonates who died of RDS were recruited as the RDS group and subgrouped into a ≤32-, a 32-36(+6)- and a ≥37-week group (n=20 per group) on the basis of gestational age. In addition, 60 neonates who succumbed to other diseases were enrolled as controls. The lung tissues were collected within 30 min after death. In situ hybridization was conducted to detect SP-B mRNA expression in the lung. The frequency of SP-B mRNA deficiency was also calculated. Among the RDS groups, the SP-B mRNA levels were significantly higher compared to those in the control group (t=7.812, P<0.001), but were comparable among RDS patients with different gestational ages (F=2.348, P>0.105). Among the control groups, the SP-B mRNA levels increased with the increase in gestational age (F=50.124, P<0.001). In the ≤32-week group, the number of cells positive for SP-B mRNA in RDS patients was markedly reduced as compared to that of the controls (t=3.185, P<0.01). In the 32-36(+6)-week group, the number of cells positive for SP-B mRNA in RDS patients was significantly smaller compared to that of the controls (t=9.342, P<0.001). In the ≥37-week group, the number of cells positive for SP-B mRNA in RDS patients was markedly smaller compared to that in the controls (t=4.238, P<0.001). Among RDS neonates, SP-B mRNA deficiency was noted in 35 patients with a frequency of 58.3%. In the control group, SP-B mRNA deficiency was noted in 8 patients with a frequency of 13.3%, which was markedly lower compared to that in the RDS group (χ(2)=26.421, P<0.001). The results of the present study therefore suggest that SP-B mRNA deficiency is involved in the pathogenesis of RDS.
