Prognostic Value of Neutrophil-to-Lymphocyte Ratio in Locally Advanced Rectal Cancer Treated with Neoadjuvant Concurrent Chemoradiotherapy and Robotic-Assisted Resection.
Article in Oncology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: The long-term outcomes of robotic-assisted surgery and the prognostic significance of the pretreatment neutrophil-to-lymphocyte ratio (NLR) in locally advanced rectal cancer (LARC) remain uncertain. This study aimed to assess the long-term outcomes of patients with LARC undergoing robotic-assisted surgery and to determine the prognostic value of pretreatment NLR. Methods: We retrospectively reviewed 252 patients with LARC who were treated at a single medical center in Taiwan between January 2012 and January 2023. All patients underwent neoadjuvant concurrent chemoradiotherapy (CRT) followed by robotic-assisted surgery with total mesorectal excision (TME). Patients were stratified into four groups on the basis of pretreatment NLRs and carcinoembryonic antigen (CEA) levels. Univariate and multivariate analyses were conducted to identify prognostic indicators for overall survival (OS) and disease-free survival (DFS). Results: Patients with a pretreatment NLR of ≥3.2 exhibited significantly worse OS and DFS compared with those with an NLR of <3.2 (OS: 94.4 vs. 116.5 months, Conclusion: Neoadjuvant concurrent CRT followed by robotic-assisted TME is an effective treatment strategy for LARC. A higher pretreatment NLR (≥3.2) independently predicted worse OS and DFS. Stratification using the NLR in combination with CEA levels may enhance prognostic accuracy for patients undergoing robotic-assisted surgery for LARC.
