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

backgroundSince the introduction of the birth control pill in 1960, Canadians have been offered a number of different options for hormonal contraceptives, yet oral contraceptives remain the most popular methods. Research from other countries indicates this may be shifting, but the last comprehensive survey of Canadian hormonal contraceptive usage was published in 2009. Therefore, the aim of this study was to determine current hormonal contraceptive usage among pre-menopausal Canadians.

methodsAn online survey was distributed to pre-menopausal females aged 19-49 years via a third-party survey company. The survey included questions on respondents' demographics and current and past hormonal contraceptive use. Prevalence of current hormonal contraceptive use was calculated by age. Chi-squared tests were conducted to determine whether there was an association between contraceptive choice and various demographic categories.

resultsResponses of 2306 female Canadians (age 33.4 ± 8.1 years) were analyzed and 29% of these respondents were currently using hormonal contraceptives. The most common choices were oral contraceptives (56.4%) and intrauterine device (IUD) (28.4%). Over 30% of hormonal contraceptive users were currently using a long-acting reversible contraceptive method.

conclusionsThese findings demonstrate a change in hormonal contraception use, notably an increase in the use of hormonal IUDs from 4 to 28% among Canadian hormonal contraceptive users over the last 15 years. This study also shows a high prevalence of alternative contraceptive options that may influence hormone levels differently than oral forms.
