Estimation of catheter insertion depth during ultrasound-guided subclavian venous catheterization.
Article in Journal of anesthesia, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundSeveral methods have been used to predict the optimal depth of central venous catheter (CVC) tip position when using the anatomical landmark technique. In the present study, we devised a simple formula to predict CVC depth using ultrasound images and chest X-ray (CXR) in patients undergoing ultrasound-guided subclavian venous catheterization.
methodsCentral venous catheterization via the subclavian vein was performed under ultrasound guidance. We measured five parameters to determine the distance between the needle insertion point and the CVC tip: insertion point to vein puncture point (A), insertion point to a skin point indicating a vertical position above the vein puncture point (B), insertion point to the clavicular notch (C), clavicular notch to the carina (D), and catheter tip to carina (E). Catheter insertion depth was then determined as follows: calculated catheter insertion depth = A - B + C + D; actual catheter insertion depth = (A - B + C + D) + E.
resultsThe calculated CVC insertion depth (mean ± SD) was 15.4 ± 1.5 cm from the needle insertion point to the carina [95 % confidence interval (CI) 15.0-15.9 cm]. Actual depth was 15.4 ± 1.5 cm (95 % CI 15.0-15.9 cm). No significant difference was observed between the calculated CVC insertion depth and the actual distance from the needle insertion point to the carina (p = 0.940).
conclusionsThe appropriate length of a CVC inserted through the subclavian vein can be estimated by a formula using ultrasound images and CXR.
