Procalcitonin Levels in Identifying Bacterial Infections in Children with and without COVID-19.
Article in Infectious diseases & clinical microbiology, 2023. 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
Objective: Elevated procalcitonin levels have been associated with bacterial infection in children. Observational studies reported high procalcitonin values in COVID-19. Data on bacterial coinfections in pediatric COVID-19 is sparse; small studies suggest a low coinfection rate. In this study, we aimed to quantify the positive predictive value (PPV) of procalcitonin in identifying bacterial infection in children with and without COVID-19. Materials and Methods: A retrospective chart review was performed for 215 children <21 years admitted to our tertiary children's hospital between February 1, 2013, and July 15, 2020, who had procalcitonin levels measured within 48 hours of admission. Confirmed bacterial infection was defined as positive blood, urine, or cerebrospinal fluid (CSF) culture, positive endotracheal culture with evidence of leukocytosis on Gram stain, or pneumonia by chest radiograph. Suspected bacterial infection was defined as confirmed bacterial infection or administration of antibiotics for >48 hours. Results: Of the 215 patients, 73 were admitted for COVID-19 (66% multisystem inflammatory syndrome in children [MIS-C], 34% acute COVID-19). The PPV of an elevated procalcitonin level >1.0 ng/mL in identifying suspected bacterial infections for those with MIS-C was 6.3% (95% CI=0-15), in acute COVID-19 was 29% (95% CI=0-62%), and in the non-COVID-19 cohort was 75% (95% CI=62-88%). For identification of confirmed bacterial infection, PPV of an elevated procalcitonin level was 0% in MIS-C, 14% (95% CI=0-40%) in acute COVID-19, and 55% (95% CI=40-69%) in the non-COVID-19 cohort. Conclusion: We found a low PPV of elevated procalcitonin level above 1 ng/mL in identifying either culture-confirmed or presumed bacterial infection in children hospitalized with COVID-19-related illness.
