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

Introduction: coronavirus disease 2019 (COVID-19) was declared a pandemic in March 2020, and most patients recover within a few days or weeks. However, some patients suffer from long COVID, which is characterized by prolonged symptoms of varying severity. Given the importance of the mining sector to the South African economy, it is critical to comprehend the impact of long COVID on the mining sector. Methods: we carried out a cross-sectional study that included data extraction from participant medical records and responses to study questionnaires. We used unique identifiers to anonymize participant information and match data from medical records to participant questionnaires. Results: data from 239 medical records and 362 questionnaires were provided by employees from three mines. About 7% of people with COVID-19 were identified as having long COVID. In addition, there was no difference in productivity between people with and without long COVID. Conclusion: our findings are not generalizable to the entire mining sector due to the limited number of participants who provided data. Additional studies that include a larger sample size are required to obtain more robust estimates of the prevalence of long COVID in the mining industry and explore potential effects of various treatment interventions for patients with long COVID.
