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
introductionTwo recent observational studies have investigated the association between androgen deprivation therapy (ADT) and rheumatoid arthritis (RA), but generated discrepant findings and had important methodological limitations. Thus, the objective of this study was to determine whether the use of ADT is associated with an increased risk of RA in men with prostate cancer. PATIENTS AND
methodsWe conducted a population-based cohort study using the United Kingdom Clinical Practice Research Datalink. The cohort included all men, at least 40 years of age, newly diagnosed with prostate cancer between 1 January 1988 and 31 March 2014, with follow-up until 30 September 2014. Exposure to ADT was treated as a time-varying variable and lagged by 1 year to account for diagnostic delays and latency. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) of RA, comparing use of ADT with non-use. Secondary analyses were conducted to assess whether the association varied according to ADT type and cumulative duration of use. Finally, we conducted several sensitivity analyses to assess the robustness of our findings.
resultsThe cohort included 32,302 men followed for a median of 3.3 years. During follow-up, 63 patients were newly diagnosed with RA, generating an incidence rate of 46.5/100,000 person-years. Compared with non-use, the use of ADT was not associated with an increased risk of RA (HR 0.84, 95% CI 0.49-1.45). In secondary analyses, the association did not vary according to ADT type or with cumulative duration of use (p trend = 0.53). The results remained consistent in sensitivity analyses.
conclusionIn this population-based study, the use of ADT was not associated with an increased risk of RA in men with prostate cancer.
