Optimal Prediction of the Central Venous Catheter Insertion Depth Targeting the Cavoatrial Junction.
Article in World journal of surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundCentral venous catheters should be positioned at the cavoatrial junction or the right atrium. If catheters are inserted to a depth derived by adding the length between the needle insertion point and the clavicular notch and the length between the clavicular notch and the carina, the catheter tip can be placed near the carina. Based on this, we aim to make a formula to place a catheter tip near the cavoatrial junction.
methodsThis prospective nonrandomized interventional study included patients who needed a central venous catheter from June 2017 to July 2018. The location of the cavoatrial junction was identified using a fluoroscopic technique. The following variables were measured: L1, the length between the needle insertion point and the clavicular notch; L2, the length between the clavicular notch and the carina; and α, the length between the carina and the cavoatrial junction.
resultsA total of 70 patients were enrolled. The mean age was 65.5 ± 11.6 years, and 62.9% were male. The mean L1 and L2 were 7.6 ± 1.4 and 7.0 ± 1.4 cm, respectively. The mean α was 4.4 ± 1.5 cm (95% CI 4.1-4.8), and it was not affected by demographic factors, such as sex, age, height or weight.
conclusionsCentral venous catheters in adult patients can be placed near the cavoatrial junction using a simple formula: the distance between the insertion point and the clavicular notch + the distance between the clavicular notch to the carina + 4.4 cm.
