Standardized endotracheal tube and intravascular access placement in infants born at 22-23 weeks gestation.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRecommendations are limited regarding the placement of oral endotracheal tube (ETT), and umbilical arterial/venous catheter (UAC/UAC) in the tiniest extremely preterm infants. We aimed to determine optimal insertion depths, and assess the impact of a too deep ETT position on outcomes.
methodsAll infants born at 22-23 weeks gestation in 2019-2024 at Uppsala University Hospital, Sweden, were evaluated radiologically for accurate positions defined as: ETT (not right-sided/in main bronchus), UAC (T6-9 or L3-4), and UVC (right atrium/inferior vena cava junction). ETT position was further analyzed in relation to time to first extubation, respiratory severity score, duration of mechanical ventilation, bronchopulmonary dysplasia, and mortality.
resultsThe cohort (n = 75; 22w n = 39; 23w n = 36) had a survival rate of 41 and 64%, respectively. The ETT was accurately placed in 75%, and lower birth weight was associated with a too deep tip position (p = 0.018). The optimal median (IQR) insertion depths were: ETT 5.5 (5.5-6.0); low UAC 6.0 (5.5-6.5); high UAC 9.6 (9.2-10.3), and UVC 5.5 (5.0-6.1) cm. ETT position was not associated with respiratory outcomes or mortality.
conclusionThe suggested insertion depths can be expected to result in accurate positioning of ETTs and umbilical lines in infants born at 22-23 weeks gestation. IMPACT: There is limited information to guide delivery room placement of endotracheal tube (ETT) and umbilical catheters (UC) in infants born at a gestational age (GA) of 22-23 weeks. An evaluation standardized insertion depths for ETT and UC, with use of x-ray based measurements of their positions, demonstrate the feasibility of using GA-based insertion depths. The suggested insertion depths can be expected to result in accurate ETT and UC tip positions in infants born at 22-23 weeks.
