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
Objectives: We investigated the characteristics of colorectal cancer (CRC) in older patients (≥ 65 years) and the immune-inflammation indexes. Methods: This study included 149 patients aged ≥ 65 years with advanced colorectal cancer, who underwent radical surgery (R0 resection). Four immune-inflammation indexes (C-reactive protein-to-albumin ratio (CAR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and neutrophil-to-lymphocyte ratio (NLR)) were calculated. We analyzed the association between immune-inflammation indexes and clinicopathological features or prognosis. Results: Tumor depth and lymph node metastasis were independent prognostic factors for recurrence-free survival (RFS) in multivariate analysis (p=0.03, hazard ratio [HR] 2.095, 95% confidence interval (CI) 1.225-3.982 and p=0.008, HR 2.209, 95% CI 1.225-3.982, respectively). Lymphatic invasion and CAR were also independent prognostic factors for overall survival (OS) in multivariate analysis (p=0.04, HR 2.197, 95% CI 1.042-4.632 and p=0.04, HR 2.174, 95% CI 1.032-4.58, respectively). Lymphatic invasion and CAR were independent prognostic factors for cancer specific survival (CSS) in the multivariate analysis (p=0.03, HR 3.004, 95% CI 1.11-8.13 and p=0.03, HR 3.087, 95% CI 1.135-8.394, respectively). Conclusions: CAR is a useful immune-inflammation index for predicting the prognosis after radical resection for advanced CRC in older patients.
