1 · What the graph read from it

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.

2 · The registry

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

Background and aim: Patient mis-centering during pediatric CT examinations can significantly affect radiation dose distribution, particularly to radiosensitive organs such as the eye lens. This study quantitatively evaluates the effect of lateral head mis-centering on eye lens dose and investigates discrepancies between measured and system-reported dose metrics using a low-cost pediatric head phantom. Materials and methods: A low-cost tissue-equivalent pediatric head phantom was constructed locally and validated using CT number comparisons with reference tissue values. Eye lens dose was measured using a pencil ionization chamber at the isocenter and at ±1-3 cm lateral displacements on two CT systems. Measured dose length product (DLP) values were compared with CT-reported DLP and air kerma-derived estimates. The data was analyzed statistically using Pearson correlation, paired sample t-tests, and one-way ANOVA. Results: Strong correlations were observed between isocenter and off-center doses ( Conclusion: Lateral mis-centering introduces systematic dose distribution asymmetry and significant discrepancies in CT dose reporting. These findings highlight the importance of accurate patient positioning and caution in interpreting system-reported dose metrics in pediatric imaging.
