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

backgroundPrevious studies have shown a decrease in cervical cancer associated with intrauterine device use. It has been hypothesized that intrauterine device use may alter the natural history of human papillomavirus infections, preempting development of precancerous lesions of the cervix and cervical cancer, but the effect of intrauterine devices on the natural history of human papillomavirus infection and subsequent development of cervical cancer is poorly understood.

objectiveThe purpose of this study was to evaluate the association between intrauterine device use and cervical high-risk human papillomavirus acquisition and clearance. STUDY

designThis is a prospective cohort study conducted from October 2000 through June 2014 among 676 sexually active young women and girls enrolled from family planning clinics in San Francisco, CA. Data were analyzed using a Cox proportional hazards model, including time-varying indicators of intrauterine device use, and adjusting for fixed and time-dependent predictor variables.

resultsA total of 85 women used an intrauterine device at some time during follow-up. Among 14,513 study visits, women reported intrauterine device use at 505 visits. After adjusting for potential behavioral confounders, there was no association between intrauterine device use and human papillomavirus acquisition (hazard ratio, 0.50; 95% confidence interval, 0.20-1.23; P = .13) or clearance of human papillomavirus infection (hazard ratio, 1.44; 95% confidence interval, 0.76-2.72; P = .26).

conclusionCurrent intrauterine device use is not associated with acquisition or persistence of human papillomavirus infection. Intrauterine device use is safe among women and girls with human papillomavirus infections and at risk for human papillomavirus acquisition. Intrauterine device use may play a role further downstream in the natural history of cervical cancer by inhibiting the development of precancerous lesions of the cervix in human papillomavirus-infected women, or enhancing clearance of established precancerous lesions.
