Updated KidZ Health Castle Formula for Multichannel Intraluminal Impedance-pH Monitoring Probe Positioning.

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
Purpose: The KidZ Health Castle Formula (KHC-F) was developed to improve the positioning of multichannel intraluminal impedance-pH probes (MII-pH). We hypothesized that the updated formula KHC-Fv2 would performs better than the original formula. This study aimed to evaluate the reliability of KHC-Fv2. Methods: A prospective cohort study was conducted to assess MII-pH probe positioning in patients aged 1 month to 18 years. Margins of error within 1 cm above or below the target position, as determined using KHC-Fv2 and compared with fluoroscopy, were accepted. Results: Eighty-four children were included in the study. The mean difference between the KHC-Fv2 and target positions was +0.25 cm cranially. The KHC-Fv2 insertion length fell within the accepted difference of ±1 cm of the target position in 67.9% of the children. This percentage increased in infants under 1 year of age (79.5%) or shorter than 100 cm (74.0%) in height. Conclusion: KHC-Fv2 demonstrated strong agreement with correct positioning and significantly reduced the need for a second radiologic control after probe repositioning, particularly in infants or children shorter than 100 cm.
