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

Many studies have focused on the association of tea consumption and the risk and progression of prostate cancer (PCa). However, the evidence is inadequate to draw robust conclusions. To shed light on these inconclusive findings, we conducted a meta-analysis. We searched the database of PubMed and Web of Science for eligible articles. The relevant data were abstracted by two independent reviewers and performed with Stata 11.0. 21 studies were included. The pooled outcomes showed that there was a significant association between tea consumption and PCa risk (OR=0.84, 95% CI (0.71-0.98)); tea consumption could reduce PCa risk in China and India (OR=0.40 and 0.48, 95% CI (0.25-0.66) and (0.24-0.97), respectively); both green and black tea consumption showed no significant effect on PCa risk (OR=0.73 and 0.95, 95% CI (0.52-1.02) and (0.82-1.11), respectively); the highest level tea consumption showed significant protective effect on the low-grade PCa (OR=0.66, 95% CI (0.46-0.93)); no significant effect was found in both localized and advanced PCa in stage subgroup analyses (OR=1.12 and 0.85, 95% CI (0.82-1.54) and (0.62-1.16), respectively). The results show that regardless of tea type, tea consumption might be a potential protective factor for the PCa, especially in China and India. Tea consumption might be the protective factor for low-grade PCa. However, more relevant studies are needed to further explore this association.
