Impact of the COVID-19 pandemic on initiation of antihypertensive drugs in Sweden: an interrupted time series study.
Article in BMJ open, 2024. 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
objectivesAntihypertensives reduce the risk of myocardial infarction and stroke. Restrictions during the COVID-19 pandemic limited access to healthcare, which may have had a negative impact on drug prescribing. This study aimed to assess the effect of the COVID-19 pandemic on the initiation of antihypertensive drugs.
designInterrupted time series study using a segmented linear regression model.
settingSwedish population assessed through linked national healthcare registers.
participants720 300 new users of antihypertensives.
interventionMarch 2020, COVID-19 pandemic onset. MAIN OUTCOMES MEASURES: The change in the initiation of antihypertensives expressed as monthly cumulative incidence, stratified by age and sex. Data on dispensed prescriptions of diuretics, beta-blockers, calcium channel blockers, ACE inhibitors (ACEi) and angiotensin receptor blockers were extracted from the Swedish Prescribed Drug Register, from March 2018 to November 2021. Initiation (new use) was defined as having no previous dispensations before March 2019. Monthly cumulative incidence in March 2019-November 2021 was calculated as the number of patients initiating each drug class in each month divided by the population.
resultsThe start of the pandemic was associated with an immediate drop in the initiation of any antihypertensive, but no sustained effects were observed, as the incidence continued to increase in the postinterruption period by +0.02% each month in both sexes. The immediate drop was statistically significant for ACEi in both sexes and all antihypertensive classes except diuretics in patients >65 years. А significant postintervention trend change was observed for initiation of diuretics (+0.013% overall), driven mainly by a significant increase in patients >65 years. Similar findings were also observed for diuretics in females (+0.02%) and ACEi (+0.03%) in patients >65 years.
conclusionsThe pandemic had an immediate negative short-term effect, but we found no major long-term negative influence of the COVID-19 pandemic on initiation of any type of antihypertensive drugs.
