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

AIMS/

introductionPoor glycemic control is known to be associated with severe infection development. This retrospective observational study examined whether glycemic control before coronavirus disease 2019 (COVID-19) onset contributes to progression from non-severe to severe COVID-19. MATERIALS AND

methodsGlycated hemoglobin (HbA1c) was measured on hospital admission in 415 patients with non-severe COVID-19. The outcome was determined from time of hospital admission to severe progression, based on clinical practice guidelines for COVID-19 in Japan.

resultsThe median value for HbA1c on admission was 6.1%, with diabetes present in 138 patients (33.3%). Among the total cohort, 93 (22.4%) progressed to severe COVID-19 with a median (interquartile range) time of 4 days (3-7 days), whereas 322 (77.6%) were discharged after 13 days (10-17 days). A multivariable Cox proportional hazards regression model showed that HbA1c level on admission was independently associated with progression to severe COVID-19 (hazard ratio for 1% increase 1.237, 95% confidence interval 1.037-1.475; P = 0.018), with findings consistent among several sensitivity analyses. In subgroup analyses, such an association was significant in patients with diabetes, as well as older age, current smoking habit, lower estimated glomerular filtration rate, higher C-reactive protein level, moderate II COVID-19, dyslipidemia and chronic respiratory disease, with no remarkable inconsistency among the subgroups. Finally, higher HbA1c level (≥7%) was more strongly associated with severe COVID-19 progression than diabetes.

conclusionsThe results suggest that poor glycemic control before COVID-19 onset contributes to progression from non-severe to severe COVID-19, even in patients with severe COVID-19 risk factors regardless of the presence of diabetes.
