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
backgroundColonic signet-ring cell carcinoma (SRCC) is a rare pathological subtype of colonic tumors. This study aims to comprehensively analyze the clinicopathological characteristics and long-term prognosis of colonic SRCC from multiple perspectives.
methodsPatients diagnosed with colonic SRCC and mucinous adenocarcinoma (MA) between 2000 and 2021 were retrieved from the surveillance, epidemiology, and end results database. Clinicopathological characteristics were compared using Chi-square tests. Overall survival (OS) and cancer-specific survival (CSS) were assessed using Kaplan-Meier curves and Cox regression analysis.
resultsA total of 29,495 patients were enrolled, including 4000 with SRCC and 25,495 with MA. Compared to MA patients, the SRCC cohort was younger, had more males, less differentiation, and higher risks of lymph node (51.2%) and distant (36.6%) metastases. Age, T stage, and M stage were identified as risk factors for lymph node metastasis in SRCC, while age, T stage, and N stage were associated with distant metastasis. SRCC patients demonstrated significantly poorer OS and CSS compared to MA patients (P < 0.001). The 1-, 3-, 5-, and 10-year OS rates for SRCC patients were 57.8, 33.3, 26.0, and 17.1%, respectively, with corresponding CSS rates of 62.8, 39.7, 34.3, and 29.3%. Multivariate Cox regression analysis revealed that age, gender, grade, TNM stage, surgical intervention, chemotherapy, and marital status were predictive of OS, while age, gender, TNM stage, surgery, and marital status were significantly associated with CSS. Notably, female SRCC patients were younger and had a lower incidence of distant metastasis compared to males. Additionally, elderly patients had a higher proportion of females and Caucasians, and a lower incidence of lymph node and distant metastases compared to non-elderly patients.
conclusionCompared to colonic MA, SRCC demonstrates unique clinicopathological features and inferior prognosis, with variations observed across age and gender. Hence, individualized treatment strategies are essential.
