Pediatric SARS-CoV-2 long term outcomes study (PECOS): cross sectional analysis at baseline.
Observational study in Pediatric research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04830852 (Pediatric SARS-CoV-2 and MIS-C Long-term Follow-up), which is not on this map. Cited by 6 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.

Abstract
backgroundPECOS is an ongoing study aimed to characterize long-term outcomes following pediatric SARS-CoV-2 infection.
methodsThis is a cross-sectional analysis of infected and uninfected cohorts at baseline. Participants (0-21 years) with laboratory-confirmed SARS-CoV-2 infection were enrolled as infected. Uninfected were defined as individuals without history or laboratory evidence of SARS-CoV-2 infection. Outcome measures included demographics, medical history, review of symptoms, physical exam, cardiopulmonary evaluation and validated psychological and developmental surveys. Primary outcomes were cohort comparisons for abnormalities on all measures.
results654 participants (541 infected, 113 uninfected) completed baseline visits by June 30, 2023. Infected participants were more likely to report constitutional (OR: 2.24), HEENT (OR: 3.74); respiratory (OR: 2.41), or gastrointestinal (OR: 2.58) symptoms. Infected had worse scores in domains of Pain, Fatigue, Global Health, Physical and Cognitive functioning, Mobility and Sleep disturbances when compared to uninfected controls using Patient Reported Outcomes. Cardiopulmonary findings were similar among cohorts.
conclusionsThe first report of this ongoing longitudinal study demonstrates that infected participants were more likely to report symptoms compared to uninfected controls, which may affect performance and quality of life of these individuals. Longitudinal data will increase understanding of long-term effects of SARS-CoV-2 infection in children. CLINICALTRIALS: gov Identifier: NCT04830852 IMPACT: This study establishes a large, diverse, prospective, longitudinal, multi-center cohort of children with history of SARS-CoV-2 infection compared to an uninfected cohort to be followed for 3 years. Cross-sectional cohort analysis at study entry showed infected participants were more likely to report constitutional, respiratory, and GI symptoms compared to uninfected controls. Infected participants were more likely to have significantly worse parent-reported performance in 6 of 10 Patient Reported Outcome Measures domains. Continued study of this cohort will help identify clinical sequelae of COVID-19, characterize the immune response to SARS-CoV-2 infection, and identify potential genetic/immunologic factors associated with long-term outcomes.
