Proper Depth of Percutaneous Central Venous Catheter via the Great Saphenous Vein for Very Low Birth Weight Infants: A Single-Center, Prospective Cohort Study.
Article in Journal of Korean medical science, 2023. 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
backgroundA proper depth of percutaneous central venous catheter (PCVC) is very important to reduce procedural time and prevent various complications in very low birth weight (VLBW) infants who require minimal handling or have a sensitive skin. The objective of this study was to suggest a formula for faster and proper insertion of PCVC in VLBWIs to prevent unintended consequences of patients' conditions.
methodsProspective data of VLBW infants admitted from June 2015 to January 2018 who had PCVC inserted via the great saphenous vein within seven days after birth were analyzed. Correlations of length of inserted PCVC with body weight, body length, and postmenstrual age at the date of PCVC insertion were determined with a linear regression analysis. Using results of this analysis, a formula to determine the optimal insertion length of PCVC was derived. Coefficient of determination was used to assess how well outcomes were replicated by the formula.
resultsThe formula to predict the proper insertion length of PCVC via the great saphenous vein at popliteal crease level was obtained as follows: Optimal Length (cm) = 3.8 × Body Weight (kg) + 11.1. With everyday movements such as flexion and extension of the lower extremities, the mean difference in catheter tip position was 7.0 ± 3.9 mm, which was not significant enough to escalate the risk of catheter tip displacement. The rate of catheter-related complications was as low as 4.9% in this study.
conclusionsThe formula derived from this study to predict the optimal PCVC insertion length could benefit VLBW infants by reducing procedural time and lowering the risk of complications.
