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
objectiveIn this study, we determined the prognostic values of magnetic resonance imaging (MRI)-based primary tumor regression and serum squamous cell carcinoma antigen (SSCC-Ag) levels 4 weeks after definitive radiotherapy (RT) in cervical squamous cell carcinoma (CSCC) patients.
methodsThis was a retrospective study involving 218 patients with histologically confirmed CSCC (stages IB-IVA). All the patients received definitive RT. Pre- and post-RT pelvic MRI and SSCC-Ag levels were measured. Locoregional control (LRC), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) were evaluated, and possible OS prognostic factors were analyzed.
resultsThe median follow-up time was 25.57 (1.73-58.93) months. Thirty-six and 68 patients died and experienced recurrence, respectively, and the primary tumors of 130 (59.6%) and 88 (40.4%) patients exhibited complete response (CR) and non-CR, respectively. The 3-year OS, DFS, LRC, and DMFS rates were significantly higher in the CR than in the non-CR patients (85.2% vs. 67.9%, 78.9% vs. 39.0%, 93.4% vs. 63.8%, and 83.4% vs. 54.5%, respectively; p< 0.05). The 3-year OS, DFS, LRC, and DMFS rates were significantly lower in the patients with high post-RT SSCC-Ag levels than in those with low post-RT SSCC-Ag levels (38.0% vs. 83.9%, 21.2% vs. 66.3%, 73.0% vs. 84.9%, and 26.5% vs. 79.0%, respectively; p<0.05). Multivariate analyses indicated that SSCC-Ag levels were an independent OS predictor (HR: 5.749, 95% CI: 2.598-12.723, p< 0.001).
conclusionPost-RT SSCC-Ag levels are OS independent prognostic factors in CSCC patients receiving RT. Timely and optimized treatment plans for CSCC patients after 4 weeks of RT are necessary when patients with persistent tumor and/or positive SSCC-Ag.
