Association of programmed death-1 gene polymorphism rs2227981 with tumor: evidence from a meta analysis.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 2 of them syntheses that pooled it.
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
To investigate the association of programmed death-1 gene polymorphism rs2227981 with tumor risk. The PubMed, Medline, Ovid Medline, EMBASE, Web of Knowledge were searched. Meta-analyses were conducted using RevMan 5.2.2 software. Total six researches involving in a total of 1427 tumor patients and 1811 healthy control people were included into this meta analysis. There was no association of PD-1 gene polymorphism with total tumor risk under four genetic models. (CT+TT vs CC, OR=1.09, 95% CI=0.80-1.49, P=0.59; CT+CC vs TT, OR=0.93, 95% CI=0.52-1.66, P=0.61; TT vs CC, OR=0.99, 95% CI=0.57-1.72, P=0.97; CT vs CC, OR=1.16, 95% CI=0.80-1.70, P=0.43). The sub-group analysis shown there were a significantly difference on association of PD-1 gene polymorphism with digestive system tumor risk between tumor patients and healthy control people, except recessive model. (CT+TT vs CC, OR=1.57, 95% CI=1.20-2.07, P=0.001; TT vs CC, OR=1.67, 95% CI=1.12-2.49, P=0.01; CT vs CC, OR=1.51, 95% CI=1.13-2.01, P=0.005). Moreover, the meta analysis results shown that there were association of PD-1 gene polymorphism with tumor risk under two models for the tumor specific occurring only in women. (CT+TT vs CC, OR=0.80, 95% CI=0.67-0.95, P=0.01; TT vs CC, OR=0.61, 95% CI=0.44-0.83, P=0.002). This study suggests that PD-1 gene polymorphism rs2227981 is associated with specific tumor types, including digestive system tumor and tumor specific occurring in woman.
