Different prognosis for stage IIB cervical cancer patients with unilateral or bilateral parametrial invasion treated with concurrent chemoradiotherapy.
Observational study in The oncologist, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo compare the survival difference between 2018 International Federation of Gynecology and Obstetrics (FIGO) stage IIB cervical cancer (CC) patients with unilateral parametrial invasion (UL) and bilateral parametrial invasion (BL) disease, and explore the significant role of parametrial invasion (PI) in prognosis prediction.
methodsA total of 506 stage IIB CC patients were identified from the multi-center study, and patients were divided into UL and BL groups according to gynecological and radiological examination. Survival outcomes were estimated and compared between 2 groups before and after propensity scoring matching (PSM). The role of upper 2/3 vaginal invasion (VI) in impacting survival probability was also assessed. The random forest (RF) model was constructed and validated to select important features related to survival outcomes and predict prognosis for these patients. The SHapley Additive exPlanation (SHAP) was further introduced to provide a better understanding toward the findings from the RF model.
resultsSignificant better 5-year overall survival (OS) was observed among patients with UL disease whether before (BL: 61.7% [95% CI: 57.0%-66.4%]; UL: 84.8% [95% CI: 82.4%-87.2%]; HR = 2.83, 95% CI: 1.90-4.20, P < 0.001) or after PSM (BL: 61.3% [95% CI: 56.6%-66.0%]; UL: 81.2% [95% CI: 77.3%-85.1%]; HR = 2.51, 95% CI: 1.56-4.04, P < 0.001). Similar findings could also be observed in terms of progression-free survival (PFS). The presence of VI didn't significantly impair the survival probability, whether in the UL or BL group (all P > 0.05). RF model was constructed, which possessed decent predictive ability both in the training (area under the receiver operating characteristic curve [AUC] = 0.893; 95% CI: 0.874-0.912) and validation cohort (AUC = 0.879; 95% CI: 0.801-0.957). PI was identified to be the paramount feature in affecting the survival outcomes for stage IIB CC patients through the Beeswarm summary plot and bar chart in SHAP analysis.
conclusionOur findings demonstrated that 2018 FIGO stage IIB CC patients with BL disease had a worse prognosis than those with UL disease, and PI was the most significant feature in prognosis prediction for these patients.
