Tea consumption and leukemia risk: a meta-analysis.
Synthesis in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis 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
Epidemiologic findings concerning the association between tea consumption and leukemia risk yielded mixed results. We aimed to investigate the association by performing a meta-analysis of all available studies. One cohort studies and six case-control studies with 1,019 cases were identified using PubMed, Web of Science, and EMBASE. We computed summary relative risks (RRs) and 95 % confidence intervals (CIs) using random effect model applied to the relative risk associated with ever, moderate, or highest drinkers vs. non/lowest drinkers. Subgroup analyses were performed based on country (China and USA). Compared with non/lowest drinkers, the combined RR for ever drinkers was 0.76 (95 % CI=0.65-0.89). In subgroup analyses, significant inverse associations were found for both China and USA studies. The summary RR was 0.57 (95 % CI=0.41-0.78) for highest drinkers. Same results were only found in China studies. No significant associations were found for moderate drinkers in overall analysis or in subgroup analyses. There was some evidence of publication bias. In conclusion, this meta-analysis suggests a significant inverse association of high tea consumption and leukemia risk. Results should be interpreted cautiously given the potential publication bias.
