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

background and purposeThe effect of green tea and coffee consumption on mortality among cardiovascular diseases survivors is unknown. We examined the association between green tea and coffee consumption and mortality among persons with and without stroke or myocardial infarction (MI).

methodsIn the Japan Collaborative Cohort Study, 46 213 participants (478 stroke survivors, 1214 MI survivors, and 44 521 persons without a history of stroke or MI), aged 40 to 79 years at baseline (1988-1990), completed a lifestyle, diet, and medical history questionnaire and were followed up regarding mortality until 2009. The Cox proportional hazard model was used to calculate the multivariable hazard ratios with 95% CIs of all-cause mortality after adjusting for potential confounding factors.

resultsDuring the 18.5-year median follow-up period, 9253 cases were documented. Green tea consumption was inversely associated with all-cause mortality among stroke or MI survivors; the multivariable hazard ratios (95% CIs) for stroke survivors were 0.73 (0.42-1.27) for 1 to 6 cups/wk, 0.65 (0.36-1.15) for 1 to 2 cups/d, 0.56 (0.34-0.92) for 3 to 4 cups/d, 0.52 (0.31-0.86) for 5 to 6 cups/d, and 0.38 (0.20-0.71) for ≥7 cups/d, compared with nondrinkers. A similar inverse association was observed for MI survivors, but not evident for those without a history of stroke or MI. Coffee consumption was inversely associated with all-cause mortality in persons without a history of stroke or MI; the multivariable hazard ratios (95% CIs) were 0.86 (0.82-0.91) for 1 to 6 cups/wk, 0.86 (0.80-0.92) for 1 cup/d, and 0.82 (0.77-0.89) for ≥2 cups/d, compared with nondrinkers. The corresponding hazard ratios (95% CIs) for MI survivors were 0.69 (0.53-0.91), 0.78 (0.55-1.10), and 0.61 (0.41-0.90). No such association was observed for stroke survivors.

conclusionsGreen tea consumption can be beneficial in improving the prognosis for stroke or MI survivors, whereas coffee consumption can also be so for persons without a history of stroke or MI as well as MI survivors.
