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
Hypoxia-inducible factor-1 (HIF-1) influences cancer progression and metastasis through various mechanisms, and HIF-1α polymorphisms are reportedly associated with many cancers; however, the associations of HIF-1α P582S and A588T polymorphisms with the risk of digestive system cancer remain inconclusive. To understand the role of HIF-1α P582S and A588T genotypes in digestive cancer development, we conducted a comprehensive meta-analysis involving 1,517 cases and 3,740 controls. Overall, the P582S polymorphism was not significantly associated with digestive system cancers in all genotypes. By contrast, the A588T polymorphism was significantly associated with digestive system cancers in the dominant model (TT/AT vs. AA: OR = 3.17, 95% CI: 1.21, 8.25; P heterogeneity < 0.001). In subgroup analysis for cancer types, the two polymorphisms were only associated with increased risk of pancreatic cancer (P582S: SS vs. PP: OR = 2.51, 95% CI: 1.31, 4.81; SS vs. PP/PS: OR = 8.73, 95% CI: 1.33, 57.1; A588T: TT vs. AA: OR = 9.30, 95% CI: 1.12, 77.6; P heterogeneity = 0.478; TT vs. AA/AT: OR = 3.14, 95% CI: 1.99, 4.97; P heterogeneity = 0.098; TT/AT vs. AA: OR = 8.65, 95% CI: 1.05, 71.6; P heterogeneity = 0.418). According to the source of ethnicity, the P582S and the A588T polymorphisms are both significantly associated with an increased risk of cancer among Caucasians in the homozygote model (SS vs. PP: OR = 2.41, 95% CI: 1.24, 4.691; P heterogeneity = 0.010; TT vs. AA: OR = 98.6, 95% CI: 4.37, 2,224; P heterogeneity = 0.040) and the recessive model (SS vs. PP/PS: OR = 9.48, 95% CI: 1.12, 80.3; P heterogeneity < 0.001; TT vs. AA/AT: OR = 82.7, 95% CI: 3.79, 1,802; P heterogeneity = 0.041). Our findings suggest that the HIF-1α A588T polymorphism is significantly associated with higher cancer risk and the P582S polymorphism is significantly associated with pancreatic cancer risk. Furthermore, the effect of both polymorphisms on digestive system cancer is more pronounced among Caucasians than that among Asians.
