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
objectiveColorectal cancer is common worldwide, and adjuvant treatment's benefit is still controversial. We designed this study to determine the role of MSI and CDX-2 status determined by immunohistochemistry (IHC) combined with the inflammatory markers and pathological parameters in predicting disease recurrence in stage II and III colon cancer.
methodsA total of 226 stage II/III colon cancer patients with a median age of 59 years who underwent initial surgery were included in this retrospective study. The pathologic assessment of MSI and CDX-2 was performed twice by immunohistochemistry (IHC) and two different pathologists. No staining/weak staining below 10% of the tumor was accepted as CDX-2 negative, and any MSI clones with weak staining below 10% were accepted as MSI-H. The laboratory parameters were noted at the initial diagnosis.
resultsOne hundred twenty-one and 105 patients were diagnosed with stage III and II colon cancer. 58.0% of patients were male, 46 (20.4%) of tumor tissue were MSS, and 17 (7.5%) were CDX-2 negative. One hundred twenty-nine tumors were localized in the right colon. Disease recurrence was significantly correlated with tumor localization, CDX-2 status, stage at diagnosis, and preoperatively median CRP and CEA levels. DFS rates for MSS patients with CDX-2 negative and positive were 36.7% and 98.1%, respectively [p < 0.001]. There was no significant correlation between MSI status and CDX-2 status. MSI status, the presence of adjuvant treatment, and systemic inflammatory markers were not significant prognostic factors for DFS. CDX-2 status [HR:0.08, CI 95% 0.03-0.17, p < 0.001 HR: 1.7, CI 95% 1.1-3.0, p = 0.03], disease stage [HR:2.6, CI 95% 1.43-4.74], and preoperatively CEA levels [HR:4.1 CI 95% 2.18-785, p < 0.001 were independent significant prognostic factors for DFS.
conclusionCDX-2 loss was an independent prognostic factor for DFS and disease recurrence in early-stage colon cancer. MSS patients with CDX-2 loss had significantly worse survival outcomes, and this might be the reason for deciding on adjuvant chemotherapy.
