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: We assessed prognostic factors of local control and progression-free survival (PFS) of patients treated for AJCC stages T1 and T2 cervical cancer using utero-vaginal brachytherapy after chemoradiotherapy. Material and methods: This retrospective single-institution analysis included patients who underwent brachytherapy after radiochemotherapy between 2005 and 2015 at the Institut de Cancérologie de Lorraine. Adjuvant hysterectomy was optional. A multivariate analysis of prognostic factors was carried out. Results: Of 218 patients, 81 (37.2%) were AJCC stage T1, and 137 (62.8%) were AJCC stage T2. 167 (76.6%) patients had squamous cell carcinoma, 97 (44.5%) patients had pelvic nodal disease, and 30 (13.8%) patients had para-aortic nodal disease. One hundred eighty-four patients (84.4%) underwent concomitant chemotherapy, while adjuvant surgery was performed in 91 patients (41.9%) and 42 (46.2%) patients had pathological complete response. Median follow-up was 4.2 years, and local control was reported in 87.8% (95% CI: 83.0-91.8) and 87.2% (95% CI: 82.3-91.3) of patients at 2 and 5 years, respectively. In multivariate analysis, T stage (hazard ratio [HR] = 3.65, 95% CI: 1.27-10.46, Conclusions: Lower dose brachytherapy may benefit AJCC stages T1 and T2 tumors, whereas higher doses are required for larger tumors and para-aortic nodal disease involvement, respectively. Pathological complete response should be associated with better local control and not surgery.
