Trends in Hospital Abortion During the First 2 Years of COVID-19 in Quebec, Canada: Results From a Population-Based Observational Study.
Observational study in Perspectives on sexual and reproductive health, 2025. 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
purposeWe investigated the extent to which the COVID-19 pandemic affected hospital abortion rates in a Canadian setting.
methodsWe obtained all abortions between 2012 and 2022 from hospital discharge data in the Maintenance and Use of Data for the Study of Hospital Clientele database for Quebec, Canada. The exposure was the pandemic (March 2020 to March 2022) compared with the preceding period (January 2012 to February 2020). The outcome included hospital-based abortions versus other pregnancy admissions. We examined if the pandemic affected monthly hospital abortion rates using interrupted time series regression. We estimated risk ratios (RRs) and 95% confidence intervals (CIs) for the association between the pandemic and hospital-based abortions, accounting for pandemic wave, abortion method, gestational age, and other patient characteristics.
resultsThere were 21,675 hospital abortions in total, including 4177 (19.3%) during the pandemic. Abortion rates decreased by 1.2 per 1000 pregnancies the first month of the pandemic and continued to decrease by 0.15 per 1000 every month thereafter. Compared with the preceding year, patients were less likely to have a hospital abortion anytime during the pandemic (RR 0.88, 95% CI 0.84-0.93), particularly during the third (RR 0.81, 95% CI 0.74-0.88) and fourth (RR 0.82, 95% CI 0.75-0.89) waves. The decrease was most apparent for instrumentation abortions, abortions before 14 weeks of gestation, and abortions among patients aged ≥ 40 years or who were socioeconomically advantaged.
conclusionsThe pandemic was associated with fewer hospital abortions before 14 weeks, as well as among older or socioeconomically advantaged patients.
