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

purposeCoffee and tea intake has been suggested to favourably affect survival of cancer patients, but studies published so far produced conflicting results. This systematic review and meta-analysis aimed to summarize the existing evidence on the association between coffee and tea consumption and cancer survival across different types of cancers.

methodsWe included 26 prospective studies (1993-2023) involving over 40,000 cancer patients from North America, Europe, and Asia. Summary hazard ratios (SHR) comparing high versus low consumption levels were calculated using random effects meta-analysis models for recurrence/progression/death.

resultsOverall, a protective effect of coffee and tea consumption on cancer survival was suggested. High coffee and/or tea intake was associated with a 24% reduction in the cancer progression risk (SHR = 0.76, 95% CI 0.67-0.87, I

conclusionThis meta-analysis suggests a protective role for coffee and tea in cancer survival, particularly for colorectal cancer. However, further research is needed to better understand their effects on other cancer types.
