Associations between aspirin use and the risk of cancers: a meta-analysis of observational studies.
Synthesis in BMC cancer, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 83 papers, 13 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
backgroundEpidemiological studies have clarified the potential associations between regular aspirin use and cancers. However, it remains controversial on whether aspirin use decreases the risk of cancers risks. Therefore, we conducted an updated meta-analysis to assess the associations between aspirin use and cancers.
methodsThe PubMed, Embase, and Web of Science databases were systematically searched up to March 2017 to identify relevant studies. Relative risks (RRs) with 95% confidence intervals (CIs) were used to assess the strength of associations.
resultsA total of 218 studies with 309 reports were eligible for this meta-analysis. Aspirin use was associated with a significant decrease in the risk of overall cancer (RR = 0.89, 95% CI: 0.87-0.91), and gastric (RR = 0.75, 95% CI: 0.65-0.86), esophageal (RR = 0.75, 95% CI: 0.62-0.89), colorectal (RR = 0.79, 95% CI: 0.74-0.85), pancreatic (RR = 0.80, 95% CI: 0.68-0.93), ovarian (RR = 0.89, 95% CI: 0.83-0.95), endometrial (RR = 0.92, 95% CI: 0.85-0.99), breast (RR = 0.92, 95% CI: 0.88-0.96), and prostate (RR = 0.94, 95% CI: 0.90-0.99) cancers, as well as small intestine neuroendocrine tumors (RR = 0.17, 95% CI: 0.05-0.58).
conclusionsThese findings suggest that aspirin use is associated with a reduced risk of gastric, esophageal, colorectal, pancreatic, ovarian, endometrial, breast, and prostate cancers, and small intestine neuroendocrine tumors.
