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
backgroundThe incidence, mortality, epidemiological characteristics, and health utilization for the diagnosis and treatment of colorectal cancer in China have shown an upward trend over time, with substantial nationwide regional variation. We aimed to observe the shift in demographic and clinical characteristics and medical utilization for the diagnosis and treatment of colorectal cancer in Guangxi from 2005 to 2014.
methodsThis study was a hospital-based retrospective survey. We enrolled patients with primary colorectal cancer in a tertiary A specialized cancer hospital diagnosed between 2005 and 2014. Patients' data were collected by trained investigators via the electronic hospital medical records. All data were calculated and analyzed using the Statistical Package for the Social Sciences version 20 statistical software.
resultsData of 1065 primary colorectal cancer patients were collected. The mean age at diagnosis was 57.33-years, and the male-to-female ratio was 1.51. The proportion of overweight/obese patients ranged from 4.95% to 23.76% between 2005 and 2014, with an upward trend. The percentage of patients with tobacco consumption increased from 4.00% to 25.45% between 2005 and 2014, and the proportion of patients undergoing CT increased from 12% to 90%; for MRI, from 0% to 25%; and for colonoscopy, from 18% to 74%. The positive rates of serum carcinoembryonic antigen with or without metastasis were 70.83% and 41.5% (p < 0.001). The positive rates of carcinoembryonic antigen and carbohydrate antigen 19-9 were positively correlated with stages at diagnosis (r = 0.31, 95% Confidence Interval: 0.18-0.34, p < 0.001) and (r = 0.35, 95% Confidence Interval: 0.21-0.47, p < 0.001), respectively.
conclusionsThe rising percentage of overweight/obese and smokers among farmers poses challenges for the prevention, control, and treatment of colorectal cancer in Guangxi. The level of serum carcinoembryonic antigen before therapy can provide information for colorectal cancer with asymptomatic metastatic disease and advanced stage.
