Impact of water on the fracture behavior of an advanced lithium disilicate.
Article in PeerJ, 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
Objective: To investigate the influence of water on the monotonic and fatigue strength of a lithium disilicate glass-ceramic. Methods: Ninety bar-shaped specimens (1.0 × 1.0 × 12.0 mm) were prepared from Advanced Lithium Disilicate (CEREC Tessera; Dentsply Sirona). Half of the specimens were stored in deionized water (W) at 37 °C for 30 days, while the other specimens stayed dry (D). A three-point bending test was carried out in a dry/wet environment (subgroup d/w) to determine monotonic strength. A stepwise fatigue test was conducted for dry-stored specimens in a dry environment (Dd) and wet-stored specimens in water (Ww). Results: For monotonic strength, the testing environment had a significant effect ( Conclusions: While storage in 37 °C water for 30 days causes ion release from lithium disilicate, it does not decrease its monotonic strength. The compressive loading in water resulted in a degradation of around 30%. The fatigue protocol in this study resulted in about 50% of the initial strength regardless of testing conditions.
