1 · What the graph read from 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.

2 · The registry

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

Folate metabolism plays an important role in carcinogenesis. Methylenetetrahydrofolate reductase (MTHFR) 677C>T polymorphism is a genetic alteration in an enzyme involved in folate metabolism, but its effect on risk of gliomas is still uncertain. To shed some light on these contradictory results from previous studies, we performed a meta-analysis of published data investigating the association between MTHFR 677C>T polymorphism and risk of gliomas. PubMed, Embase, and Web of Science databases were searched for eligible case-control studies. Odds ratios (ORs) and 95 % confidence intervals (CIs) were used to assess the strength of this association. Ten individual case-control studies from six publications with a total of 1,786 cases and 2,076 controls were included into this meta-analysis. There was no obvious heterogeneity under all comparison models of this meta-analysis. Meta-analysis of those ten studies showed that there was no obvious association between MTHFR 677C>T polymorphism and risk of gliomas under all five genetic models (for T versus C, OR = 1.00, 95 % CI 0.90-1.12, P OR = 0.959; for TT versus CC, OR = 1.02, 95 % CI 0.82-1.27, P OR = 0.870; for CT versus CC, OR = 1.02, 95 % CI 0.89-1.18, P OR = 0.733; for TT+CT versus CC, OR = 1.02, 95 % CI 0.90-1.16, P OR = 0.781; for TT versus CT+CC, OR = 0.99, 95 % CI 0.81-1.21, P OR = 0.902). There was also no obvious association between MTHFR 677C>T polymorphism and risk of gliomas in the sensitivity and subgroup analyses of Caucasians. There was no risk of publication bias in this meta-analysis. The evidence from our meta-analysis supports that there is no association between MTHFR 677C>T polymorphism and risk of gliomas.
