Neonatal presumed septic pulmonary embolism associated with a peripherally inserted central catheter: a case report.
Article in Frontiers in pediatrics, 2026. 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
Septic pulmonary embolism (SPE) is a rare complication of peripherally inserted central catheters (PICC), with few neonatal reports. We present a premature infant who developed recurrent apnea and hypoxemia during PICC indwelling. Imaging revealed bilateral thick-walled cavitary lesions. Although two consecutive conventional peripheral blood cultures remained negative, MSSA was identified from PICC tip culture, deep sputum culture, and NGS analysis of peripheral blood, PICC intraluminal blood, and deep sputum samples. The infant recovered after 39 days of antimicrobial therapy, including five weeks of targeted linezolid. This case suggests that PICC surface biofilms were the most probable source of septic emboli causing occult SPE, underscoring the importance of considering catheter-related pulmonary embolism in neonates with unexplained respiratory deterioration.
