Asthma exacerbation prevalence during the COVID-19 lockdown in a moderate-severe asthma cohort.
Trial report in BMJ open respiratory research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 papers.
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
introductionFollowing the recent COVID-19 lockdown, a reduction in emergency healthcare visits was reported. Infectious diseases were less often diagnosed, while it was not clear if this was due to a decrease in prevalence or a decrease in emergency healthcare visits due to fear of COVID-19.
methodsThis study comprises a follow-up from a recently finished randomised controlled trial, to gain insight into the prevalence of asthma exacerbation and fear of COVID-19 in patients with moderate-severe asthma and controls in the Netherlands. Participants, patients with asthma and controls, were invited to fill out a short survey by email or post. Exacerbation frequencies until 1 July 2020 were verified with the hospitals' and general practitioners' medical records, pharmacies and patient interviews.
resultsIn quarter 2 of 2020, mean exacerbation frequency per patient was significantly lower (χ
conclusionIn conclusion, we found a significantly reduced asthma exacerbation frequency during COVID-19 social distancing measures compared with previous years. Patients with asthma also showed more anxiety towards (acquiring) COVID-19 infection. TRIAL REGISTRATION NUMBER: NL8576.
