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
Objective: To study and predict the risk of further vaginal lesions after surgery in patients with HPV-associated cervical cancer. Methods: Medical records of women who underwent surgery for cervical cancer between January 2018 and December 2022 at the Obstetrics and Gynecology Hospital of Fudan University were analyzed. Incidence and genotype of persistent HPV infection were recorded and patients with further vaginal lesions were analyzed for clinicopathological risk factors. Of the patients, 70% were randomly grouped into a training cohort, and predictive prognostic models for vaginal lesions were constructed through machine learning. The model with the highest area under the receiver operator curve (AUC) was screened out in the testing cohort. The nomogram and its calibration curve presented the risk of sequela vaginal lesions. R 4.2.0 software was used for all data processing. Results: Within five years after surgery, 29.94% of patients remained persistently infected with HPV, with annual rates fluctuating around 22%. In addition, 10.2% of patients were diagnosed with vaginal intraepithelial neoplasia (VaIN), and 320 cases (78.35%) were low-grade squamous intraepithelial lesions (LSIL). The annual incidence of vaginal lesions decreased gradually from 6.97% in the first year (Y1) to 2.96% at year 5 (Y5). Ovarian preservation (OP) during hysterectomy and adenocarcinoma histology were found to be protective from further vaginal lesions, while elder age, FIGO stage II, and positive vaginal incision margin were significant risk factors. As for persistent HPV infection, both single and multiple genotype remarkably increased the risk of vaginal lesions, and a α-9 HPV infection (OR = 18.20) brought higher risk than non-α-9 HPV (OR = 11.76). Then we built three predictive models; multiple logistic regression was optional, with its AUC at 0.7955 in the ROC curve. Conclusion: The predictive model constructed in our study could identify populations at high risk of vaginal lesions and precisely guide clinical interventions.
