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
Metformin is a classical oral hypoglycemic drug, often recommended as the first-line therapy for type 2 diabetes mellitus (T2DM). Previous research has shown that the efficacy of metformin is associated with the genetic polymorphisms of patients. Considering the role of G6PC in gluconeogenesis and glycogenolysis, this study aims to investigate the association of G6PC rs161620 and rs2229611 with metformin efficacy in T2DM patients who take metformin only. According to the decrease of HbA1c, 116 T2DM patients receiving metformin monotherapy were divided into two groups: response group (the decrease of HbA1c by at least 1.5% after 3 months) and non-response group (the decrease of HbA1c < 1.5%). SNPscan technology was used to genotype. There were significant differences in rs161620 and rs2229611 presented in genotype frequency (p = 0.027 both) between the response group and the non-response group. According to the results of logistic analysis, the genetic polymorphisms of G6PC rs161620 or rs2229611 could influence the hypoglycemic effect of metformin in T2DM patients. We found that the decreasing values of PBG and HbA1c in G6PC rs161620 (C > A) or rs2229611 (T > C) mutants were significantly more than those in wild-type individuals, which means the more effective genotypes of metformin are CA/AA of rs161620 and TC/CC of rs2229611. This study suggested that the G6PC rs161620 and rs2229611 genetic polymorphisms were significantly associated with metformin efficacy in Chinese T2DM patients.
