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

backgroundBone and joint infections (BJIs) in neonates are rare but serious conditions associated with significant orthopedic complications. Diagnosis is challenging due to nonspecific clinical manifestations, often leading to delayed treatment and poor outcomes. This study aimed to analyze the clinical characteristics, management, and outcomes of neonates with BJIs to improve early diagnosis and guide clinical decision-making.

methodsWe performed a single-center, retrospective review of 20 neonates (aged ≤ 35 days) hospitalized with BJIs between 2017 and 2025. Data on demographics, clinical presentation, laboratory and imaging findings, treatment, and outcomes were collected and analyzed.

resultsThe mean age was 21.2 days, and 65% of the neonates were male. Pseudoparalysis was the most common presenting symptom (observed in 95% of cases). Pathogens were identified in 14 of the 20 cases (70%), with Staphylococcus aureus being the most prevalent (identified in 11 patients, 55%). Concurrent bone and joint infections were observed in 65% of the patients. Ultrasound demonstrated a high detection rate (95%). Surgical drainage was performed in 12 patients (60%), who presented with significantly higher C-reactive protein levels and a higher culture-positive rate than did the nonsurgical group. With one patient lost to follow-up, data were available for 19 patients, of whom five (26.3%) experienced complications.

conclusionsNeonatal BJIs often present with nonspecific signs, among which pseudoparalysis is a key indicator. Ultrasound is a sensitive, first-line imaging tool. Early surgical intervention should be considered for patients with concurrent arthritis and significantly elevated inflammatory markers, as it is associated with higher pathogen identification and provides effective source control.
