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

In the light of the relationship between the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and thyroid cancer (TC) exist objection, a meta-analysis of the MTHFR C677T polymorphism with thyroid cancer risk was performed. All the available studies were identified through a search of the PubMed, Embase, Web of Science, and Chinese Biomedical Literature Database (CBM) up to March 2014. The association between the MTHFR C677T polymorphism and thyroid cancer risk was conducted by odds ratios (ORs) and 95 % confidence intervals (95 % CIs). A total of five independent studies with 2,554 cases and 2,671 controls were included in our meta-analysis. Significant association was found between MTHFR C677T polymorphism and thyroid cancer risk in recessive model in overall populations (TT vs. TC/CC: OR = 1.88, 95 % CI = 1.59-2.21, P = 0.00), but there was no association between MTHFR C677T polymorphism and thyroid cancer risk found in other four models in overall populations (T vs. C: OR = 1.25, 95 % CI = 0.96-1.62, P = 0.10; TT vs. CC: OR = 1.11, 95 % CI = 0.93-1.33, P = 0.26; TC vs. CC: OR = 1.23, 95 % CI = 0.84-1.82, P = 0.29; TT/TC vs. CC: OR = 1.28, 95 % CI = 0.89-1.84, P = 0.19). In the subgroup analysis base on the ethnicity, the results suggested that MTHFR C677T polymorphism was significantly associated with thyroid cancer risk both in Caucasian and Asian populations in recessive model: (Caucasians: TT vs. TC/CC: OR = 2.28, 95 % CI = 1.11-4.67, P = 0.025; Asians: TT vs. TC/CC: OR = 1.86, 95 % CI = 1.57-2.20, P = 0.00). In conclusions, our meta-analysis suggested that the MTHFR C677T polymorphism is associated with thyroid cancer both in Caucasians and Asians.
