Evaluation of Strength of Different Crowns In Rehabilitation of Mandibular Posterior Regions: A Comparative Study.
Article in Journal of pharmacy & bioallied sciences, 2025. 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
Objective: To evaluate the strength of different crown materials used in the rehabilitation of mandibular posterior regions and to compare their performance under realistic conditions. Methods: A total of 90 crowns made from three materials-zirconia, lithium disilicate, and metal-ceramic-were tested using compressive load testing. Crowns were placed on standardized resin dies simulating mandibular molars and subjected to cyclic loading and fracture strength assessment. Results: Zirconia crowns exhibited the highest fracture resistance, followed by metal-ceramic and lithium disilicate crowns. Statistically significant differences were observed between the groups ( Conclusions: Zirconia crowns offer superior strength, making them ideal for mandibular posterior rehabilitation. However, the choice of material should also consider aesthetic requirements and patient-specific factors.
