Quantitative cervical elastography: a new approach of cervical insufficiency prediction.

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
objectivesTo establish methodological criteria for the clinical application of E-cervix technology in non-pregnant women, evaluate cervical differences between non-pregnant CI patients and normal women, and explore the predictive value of E-cervix for CI in non-pregnant women.
methodsIn all, 46 non-pregnant women with CI and 46 non-pregnant women with full-term pregnancy experience were included. Elastic parameters (HR, IOS, EOS, IOS/EOS, CL) of the cervix were measured by transvaginal examination with a mid-sagittal section as the ROI, followed by examination of the whole cervix. The pressure of the probe on the cervix was divided into three levels. The elastic data of three consecutive images were separately obtained by two doctors for three pressure levels. Image stability and the effects of pressure were evaluated and the repeatability of the measurements was tested. In the case and control groups, cervical elasticity images were selected by standardized operation methods. Differences in the parameters between the two groups were determined and the diagnostic efficiency of each parameter was analyzed.
resultsThe HR, IOS, and EOS showed significant differences when measured on different sequential images obtained by continuous mapping (p < 0.05). The elastic parameters obtained from the first and last two images were significantly different (p < 0.05) and there were no significant differences between the elastic parameters obtained from the last two images (p > 0.05). The HR, IOS, EOS, and IOS/EOS showed significant differences among the pressure levels (p < 0.05), while the IOS showed a significant difference only between grades 0 and 2 (p < 0.05). E-cervix showed good repeatability within and among operators. The elastic parameters obtained by E-cervix in the CI group and control group were significantly different. ROC curve analysis showed that the HR was the most sensitive index for diagnosing CI.
conclusionIn E-cervix data acquisition, the first image should be excluded and the probe should not put pressure on the cervix. E-cervix has good retest and inter-observer reliability. Compared with normal women, CI patients showed a relatively softer and shorter cervix. E-cervix can be used as an important diagnostic tool for assessing cervical strain.
