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
purposeTo detect the methylation of Dickkopf-associated protein 1 (DKK-1) gene promoter in cervical exfoliated cells and to study its clinical significance in cervical squamous cell carcinoma (CSCC) and its relationship with high-risk HPV infection.
methodsMethylation-specific PCR (MSP) was utilized to detect the methylation of DKK-1 gene promoter in cervical exfoliated cells from 40 patients with CSCC and 40 patients with chronic cervicitis in the Affiliated Hospital of Inner Mongolia Medical University. The methylation rate of DKK-1 gene promoter in different clinicopathological factors and its relationship with high-risk HPV infection was compared, and different detection methods were compared.
resultThe degree of methylation of DKK-1 gene promoter in CSCC group was significantly higher than that in cervicitis group (P < 0.05). In CSCC group, the degree of methylation was significantly different in high-risk HPV infection, histological differentiation, tumor size, lymph node metastasis and the International Federation of Gynecology and Obstetrics (FIGO) staging (all P < 0.05). The degree of methylation is not related to the type of high-risk HPV infection (P > 0.05). The one-year survival rate of CSCC patients with high-risk HPV positive and DKK-1 gene promoter methylation is relatively low, only 74.1%. The sensitivity, specificity and accuracy of DKK-1 gene methylation combined with high-risk HPV detection were 96.7%, 78.0% and 85.0%, respectively.
conclusionMethylation of DKK-1 gene promoter in cervical exfoliated cells of patients with CSCC is related to high-risk HPV infection and different clinicopathological factors, but the degree of methylation of DKK-1 gene is not related to the type of high-risk HPV infection. It may become an indicator different from HPV typing detection, which may play a shunt role in suggesting whether further invasive cervical examination is needed and reduce cervical invasive examination and overtreatment. It may be related to the survival rate of patients, which can be used to estimate the development and prognosis of CSCC and may play a good role in early warning in follow-up monitoring of CSCC after treatment. DKK1 gene methylation combined with HPV detection can improve the sensitivity, specificity and accuracy of diagnosis, which may improve the detection rate of early CSCC and make up for the deficiency of HPV and TCT detection. That may become a non-invasive screening method for CSCC.
