Age estimation through sternal fusion and costal cartilage ossification using MSCT in a Croatian population: model development and application.
Article in International journal of legal medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This study aimed to test age-related changes in sternal fusion and sternal-rib cartilage ossification on multi-slice computed tomography (MSCT) images of the Croatian population. The additional aim was to develop models to estimate age and provide an interface for the model's application and validation. This retrospective study was conducted on 144 MSCT images of the sternal region, and the developed models were tested on 36 MSCT images. We scored manubrium-mesosternal joint fusion (FM), xiphoid process and mesosternum fusion (FX), ossification of the first costal cartilage (OF), ossification of the second to seventh costal cartilages at the rib ends (OR), and ossification of the second to seventh costal cartilages at the sternal ends (OS). All sternal-rib cartilage ossification phases and sternal body and xiphoid process fusion scores showed statistically significant age differences (P < 0.001), except manubrium-mesosternal joint fusion. The final model that combined regression and classification using FM, FX, OR, OS, and sex obtained a 95% prediction interval (PI) coverage of 94.46% on the cross-validation (cv) and 91.67% on the test set with an average PI width of 42.29 and 42.95 years respectively. We also developed a Python Flask app called CroSterna: Age estimation from sternal fusion and rib ossification in the Croatian population ( https://crosterna.onrender.com/ ) to facilitate the estimation for professionals.
