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
backgroundThis study aims to investigate the expression of galectin-1 and vascular mimicry (VM) in rectal cancer tissues, and to assess their predictive value in the prognostic evaluation of patients with rectal cancer.
methodsImmunohistochemistry (IHC) and CD34-periodic acid solution (PAS) double staining were used to detect galectin-1 expression and the formation of VM in rectal cancer tissues from 94 patients with stage I-III rectal cancer and their corresponding paracancerous tissues. We also analyzed the relationship between the expression of galectin-1, VM, various clinicopathological parameters, and the prognosis of rectal cancer patients, as well as their influence on the overall survival (OS) of rectal cancer patients.
resultsAmong the 94 tissue specimens from rectal cancer patients, 43 had positive expression of galectin-1 and 19 had positive expression of VM. There was a positive correlation between VM and galectin-1 expression in rectal cancer tissue. Galectin-1 expression in rectal cancer tissue and the formation of VM were related to tumor differentiation, staging, lymph node metastasis, and intravascular tumor thrombus (P<0.05). Kaplan-Meier analysis showed that the OS time of rectal cancer patients in the galectin-1 positive expression group was shorter than the galectin-1 negative expression patients, and the difference between the 2 groups was statistically significant (P=0.003). The OS time of patients with rectal cancer in the VM positive expression group was shorter than the VM negative expression group, and the difference between the two groups was statistically significant (P<0.001). The OS time of the galectin-1 and VM negative expression group was 57.33±1.13 months, and the OS time of the galectin-1 and VM positive expression group was 43.21±3.97 months, while the OS time of the galectin-1 positive expression and VM negative expression group was 55.42±2.23 months, and the difference between the three groups was statistically significant (P<0.001). Multi-factor analysis results indicated that invasion depth and VM expression were independent risk factors that affected the OS of patients with rectal cancer.
conclusionsGalectin-1 and VM expression in rectal cancer tissues may predict poor prognosis in patients after radical surgery. Galectin-1 and VM may therefore become potential new targets for rectal cancer treatment.
