COVID-19's causal impact on child abuse and socioeconomic status: a Bayesian time series study.
Article in Pediatric research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe COVID-19 pandemic intensified psychosocial stressors, potentially contributing to increased rates of child abuse. This study aimed to compare trends in child abuse/traumatic brain injury (TBI) admissions and socioeconomic status before and after the pandemic.
methodsA 7-year retrospective study was conducted at a Level-1 Pediatric Trauma Center. TBI cases were identified using ICD-10 codes based on the modified CDC framework. Neighborhood disadvantage and injury severity were measured using the Social Deprivation Index (SDI) and Injury Severity Score (ISS), respectively, with higher scores indicating greater disadvantage and severity. A Bayesian structural time series (BSTS) model was employed to assess the causal impact of COVID-19 on monthly child abuse/TBI admissions, SDI, and ISS.
resultsThe study included 560 child abuse cases, with 62.3% involving TBI. Before COVID-19, monthly admissions averaged 5.89 for child abuse and 3.70 for child abuse with TBI, with corresponding SDI scores of 60.07 and 57.60. During the COVID era, monthly averages rose to 8.77 and 5.58 (p = 0.001, p < 0.001), and SDI scores increased to 66.32 and 61.60 (p = 0.053, p = 0.370). BSTS analysis inferred a causal impact of COVID-19 on monthly child abuse admissions (p = 0.001), monthly child abuse admissions sustaining TBI (p = 0.001), an upward trend in average monthly SDI scores (p = 0.033), and a decrease in average monthly ISS (p = 0.001).
conclusionsThe study indicates a significant increase in child abuse/TBI admissions and heightened neighborhood disadvantage during the COVID-19 pandemic. IMPACT: This study uses Bayesian structural time series analysis to assess the COVID-19 pandemic's causal impact on child abuse and traumatic brain injury (TBI) admissions. The pandemic is linked to increased child abuse admissions and TBI cases, correlating with worsening socioeconomic conditions indicated by higher Social Deprivation Index scores. Admissions did not rise significantly during the early pandemic (first 3 months, p = 0.160), but mid-to-late phases showed a significant increase (p = 0.001). Injury severity, as measured by Injury Severity Score, declined, suggesting less severe injuries during the pandemic. These findings emphasize the need for proactive interventions and continuous surveillance to protect vulnerable populations.
