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

We assessed blood pressure (BP) changes during fiscal years (April to March of the following year) 2015-2020 to clarify the effect of the state of emergency due to the coronavirus disease 2019 (COVID-19) pandemic in 2020. We then considered BP in 2019 separately, as the Japanese hypertension guidelines were updated in 2019. The present retrospective cohort study extracted data from 157,510 Japanese individuals aged <75 years (mean age: 50.3 years, men: 67.5%) from the annual health check-up data of the DeSC database. The trends in BP were assessed using a repeated measures linear mixed model. After adjusting for the month of health check-ups to exclude seasonal BP variation, systolic BP linearly increased during fiscal years 2015-2018. From the value estimated by the trend in 2015-2018, systolic BP was lower by ≤1 mmHg in fiscal year 2019 among the treated participants. Meanwhile, systolic/diastolic BP (95% confidence interval) increased by 2.11 (1.97-2.24)/1.05 (0.96-1.14) mmHg for untreated women (n = 43,292), 1.60 (1.51-1.70)/1.17 (1.11-1.24) mmHg for untreated men (n = 88,479), 1.92 (1.60-2.23)/0.46 (0.25-0.67) mmHg for treated women (n = 7855), and 1.00 (0.79-1.21)/0.39 (0.25-0.53) mmHg for treated men (n = 17,884) in fiscal year 2020. These increases remained time-dependent covariates after adjustments for age, body mass index, alcohol consumption, smoking, physical activity, and blood sampling indices. Social change due to the pandemic might have increased BP by approximately 1-2/0.5-1 mmHg. Meanwhile, only a slight decrease in BP was observed immediately after the guideline update in Japan.
