Coffee and Tea Consumption in Relation to Risk of Rheumatoid Arthritis in the Women's Health Initiative Observational Cohort.

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
objectiveThe aim of this study was to evaluate whether tea or coffee consumption is associated with an increased risk of older-onset rheumatoid arthritis (RA) using the Women's Health Initiative Observational Study.
methodsThe Women's Health Initiative Observational Study is a longitudinal prospective cohort study conducted from 1993 to 1998. There were 76,853 women who completed a self-administered questionnaire about their daily consumption of tea and coffee. One hundred eighty-five women self-reported and validated incident cases of RA were observed after 3 years of observation. Multivariable Cox proportional hazards models were performed to assess the relationship between consumption habits and disease incidence. Trend tests were calculated using categorical variables modeled as a continuous variable without collapsing.
resultsThere was no increase in the hazard ratio for incident RA in those participants who drank coffee compared with those who did not. The amount of coffee consumed and the method of preparation (caffeinated/decaffeinated; filtered/unfiltered) also did not alter the risk of incident RA. There was a positive association of incident RA and caffeinated tea consumption in the trend test (p = 0.03). When assessing any caffeinated tea consumption versus no tea consumption, the hazard ratio for incident RA was 1.40 (confidence interval, 1.01-1.93; p = 0.04).
conclusionsIn a large prospective cohort of older women, there was no association between coffee consumption and incident RA. A small association between daily caffeinated, nonherbal tea consumption and incident RA was found.
