Complications and risk factors of neonatal peripherally inserted central catheters lines.
Article in BMC 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
backgroundPeripherally inserted central catheters (PICCs) are widely used in neonatal intensive care units (NICUs) but are associated with a broad spectrum of complications. Evidence regarding their incidence and risk factors in neonates remains limited.
methodsWe conducted a retrospective cohort study including 1800 neonates who underwent PICC placement between 2018 and 2025, accounting for 24,660 catheter-days. Mechanical, infectious, thrombotic, and other PICC-related complications were systematically recorded. Incidence densities were calculated per 1000 catheter-days. Multivariable logistic regression was used to identify independent predictors of catheter-related bloodstream infection (CRBSI) and non-technical complications.
resultsAt least one PICC-related complication occurred in 58.2% of neonates (41.8 per 1000 catheter-days). Catheter tip malposition was the most frequent event (47.8%), followed by occlusion or edema (18.3%) and migration or dislodgement (12.2%). CRBSI occurred in 6.2% of infants, with an incidence of 4.3 per 1000 catheter-days. Cephalic vein insertion was strongly associated with malposition (adjusted odds ratio [aOR] 7.30; 95% CI 5.90-9.02). Prolonged catheter dwell time independently increased the risk of CRBSI (aOR 1.10 per day; p < 0.001), while total parenteral nutrition and intravenous anticonvulsant therapy were additional independent predictors. Non-technical complications were independently associated with lower birth weight, catheter malposition, hyperosmolar medication exposure, and longer dwell time.
conclusionsPICC-related complications are common in neonates, with malposition representing the predominant event and associated with subsequent adverse outcomes. Optimizing insertion site selection, minimizing catheter dwell time, and cautious use of hyperosmolar infusions may reduce PICC-related morbidity in the NICU.
