Retail demand for emergency contraception in United States following New Year holiday: time series study.
Article in BMJ (Clinical research ed.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo estimate the increase in sales of emergency contraception following the New Year's Eve/New Year's Day holiday.
designTime series analysis using autoregressive integrated moving average (ARIMA) model.
settingTraditional (that is, "bricks and mortar") retail outlets-grocery stores, drug stores, mass merchandisers, club stores, dollar stores, and military outlets-in the United States from 2016 to 2022. DATA SOURCE: Marketing data on weekly aggregated sales of items classified as emergency contraception gathered between 2016 and 2022 (n=362). On the basis of dates, weeks were classified as following the New Year holiday (n=6) or not (n=356).
main outcome measureWeekly sales of levonorgestrel emergency contraception per 1000 women of reproductive age in the US population.
resultsSales of levonorgestrel emergency contraception significantly increased after the New Year holiday (0.63 (95% confidence interval 0.58 to 0.69) unit increase per 1000 women aged 15-44). Holidays that share some aspects of the elevated risks of unprotected sexual intercourse with the New Year holiday (Valentine's Day, St Patrick's Day, US Independence Day) were associated with increased sales, albeit to a lesser degree, with respective sales increases per 1000 women aged 15-44 of 0.31 (0.25 to 0.38), 0.14 (0.06 to 0.23), and 0.20 (0.11 to 0.29). Holidays without these expectations (Easter, Mother's Day, Father's Day) were not significantly associated with sales of levonorgestrel emergency contraception.
conclusionsIncreased sales of emergency contraception following the New Year's holiday suggest that this period is associated with increased risks of unprotected vaginal intercourse compared with other holidays. Targeting behavioral risks, prevention strategies to mitigate sexual violence, and improving access to contraception around holidays may limit the risks associated with unprotected vaginal intercourse.
