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
Purpose: This study aims to investigate the predictive value of shear-wave elastography (SWE) parameters, combined with cervical morphological parameters [cervical length (CL) and anterior cervical angle (ACA)] for spontaneous preterm birth (sPTB) in patients with cervical insufficiency following transvaginal cervical cerclage, thereby providing a reference for early clinical intervention. Patients and methods: Clinical data of 662 pregnant women diagnosed with cervical insufficiency who underwent vaginal cervical cerclage at Zhenjiang First People's Hospital between January 1, 2018, and October 31, 2024, were retrospectively collected. Participants were divided into a preterm birth group (98 cases, <37 weeks) and a full-term group (564 cases, ≥37 weeks) based on gestational age at delivery. All patients underwent transvaginal ultrasound within 24 h before cerclage and during postoperative follow-up (19-36 Results: CL and SWE parameters (AE, AI, PI, PE) were significantly lower in the preterm group than in the full-term group, while ACA was significantly higher (all Conclusion: SWE parameters combined with cervical morphological parameters are closely associated with sPTB after cerclage in patients with cervical insufficiency. The combination of these three indicators significantly improves predictive performance, providing reliable imaging-based evidence for precise pregnancy risk assessment and individualized intervention strategies. Plain language summary: Cervical shear-wave elastography parameters, in combination with cervical morphological parameters (cervical length and anterior cervical angle), can effectively predict the risk of spontaneous preterm birth in patients with cervical insufficiency after cerclage. The predictive model integrating these indicators demonstrates high accuracy and provides a reliable tool for clinical assessment, supporting individualized pregnancy monitoring and intervention strategies.
