A preliminary study on quantitative assessment of apical lesion area.
Article in American journal of translational research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo establish a quantitative method for calculating the area of apical lesions, thereby enabling a more precise assessment of the extent of apical lesions.
methodsThree observers annotated periapical radiographs using a proprietary web-based annotation platform. Root outlines and lesion boundaries were delineated to obtain both the absolute lesion area (S
resultsAnnotations were completed on 126 radiographs containing 490 tooth roots. PAI scores demonstrated moderate intra-observer (Cohen's kappa range: 0.45-0.58) and inter-observer (Fleiss' kappa: 0.41) reliability. In contrast, ICC values for both S
conclusionsThis study established a relatively quantitative method for assessing apical lesions. S
