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

introductionIncidence rates of bladder cancer are notably higher in men than in women. While there is evidence that reproductive and hormonal risk factors may influence risk of bladder cancer, data are inconclusive. MATERIALS AND

methodsWe examined reproductive, menstrual and hormonal use history in our population-based case-control study of bladder cancer in New Hampshire (NH), USA (n=207 women cases and n=463 women controls). Additionally, we performed a meta-analysis of the published literature. We used unconditional logistic regression analysis to compute adjusted odds ratios associated with each risk factor in the NH study. We combined these estimates with those from the published literature using inverse variance effects models.

resultsIn the NH study, a slightly decreased odds ratio was found among women who had ever had a birth compared to nulliparous women and an elevated odds ratio among women who underwent surgical menopause (bilateral oophorectomy), especially at an early age. No overall associations were found with oral contraceptive use or hormone replacement therapy. These findings were generally in agreement with the meta-analytic results for which the combined relative risk (RR) estimate was reduced among ever parous women (combined RR estimate for ever parous versus nulliparous=0.66, 95% confidence intervals [95% CI] 0.55-0.79) and elevated among those undergoing an early menopause (combined RR estimate for early versus late menopause=1.59, 95% CI 1.31-1.92). No consistent risk was observed for the other factors. DISCUSSION: Some reproductive and menstrual factors appear to be related to the incidence of bladder cancer among women; but whether effects are due to female hormones is uncertain.
