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

Background and purpose - While many other countries implemented strict regulations and restrictions for their citizens during the 1st wave of the Covid-19 pandemic, Sweden maintained a more restrained approach. The Swedish Public Health Agency emphasized individual responsibility and pushed for behavioral changes. With strict lockdown a 77% decrease in ankle fracture incidence has been reported. We investigated whether there was a change in the incidence of ankle fractures seen at 7 selected hospitals during the Covid-19 pandemic 2020.Patients and methods - Data on all ankle fractures treated at 7 selected departments during March 15 through June 15, 2020, and for the same period in the preceding 3 years (2017-2019), was retrieved from the Swedish Fracture Register. The number of fractures during the whole period and subsequent 30-day periods were compared between 2020 and 2017-2019, including subgroup analyses of age and sex.Results - The monthly rate of ankle fractures was reduced by 14% in 2020 (139 fractures) compared with 2017-2019 (161 fractures). Women had a 16% decrease and patients aged > 70 years had a 29% decrease. During the 1st 30-day period, a 26% decrease in fractures was seen.Interpretation - During the 1st wave of the Covid-19 pandemic, a moderate decline in the number of ankle fractures was seen. Women and patients aged > 70 years displayed the greatest reduction. The greatest reduction in incidence of fractures was seen during the 1st 30-day period. This indicates greater adherence to government recommendations regarding social distancing in these subgroups and during the 1st month of the pandemic. Changes in ankle fracture incidence may be a measure of lockdown extent.
