Incidence and immediate consequences of electrical shocks among Danish electricians: a cohort study.
Article in BMJ open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThe health-related consequences of electrical shocks are mostly studied in patients from selected cohorts in hospital burn units, by making internal comparisons of subgroups, but without comparing them to unexposed individuals, or considering information regarding the preinjury health of the injured persons. Often, little is known about the details of the electrical shocks. Our purpose was to do a longitudinal study of Danish electrical workers, to monitor exposure to electrical shocks weekly over a 6-month period and to determine whether these shocks have short-term, health-related consequences.
designProspective cohort study with weekly measurements.
settingMembers of the Danish Union of Electricians.
participantsOf the 22 284 invited, 6960 electricians (31%) participated in the baseline data collection, and the participation rate in the weekly follow-up ranged from 61% to 81% during the 6 month follow-up. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome measure was an electrical shock and secondary outcomes were the immediate health-related consequences of the shocks.
resultsA total of 2356 electrical shocks were reported by 1612 (23%) of the participants during the 26-week follow-up. Alternating current and voltage below 1000 V were the most common forms of electricity. In most cases, the fingers/hands were the entry and exit points, but many were unable to specify the exit point. The participants categorised 73% of the electrical shocks as 'not at all severe', and most of the shocks did not cause any immediate physical damage. However, flashbacks were more common than physical consequences. Only a few of the participants contacted health services following an electrical shock, and even fewer were absent from work.
conclusionNearly one-fourth of Danish electricians experienced one or more electrical shocks during a 26-week period, but most of the shocks are not perceived as severe, and have only limited immediate consequences.
