Corrosion Behavior of Ti-Nb-Zr-Si Alloy after One-Year Exposure to Simulated Inflammatory Conditions.
Article in ACS omega, 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
Long-term corrosion and elemental release are critical factors controlling the clinical reliability of titanium-based implants, particularly under inflammatory conditions. In this study, commercially pure titanium (CP-Ti), Ti-6Al-4V, and Ti-Nb-Zr-Si (TNZS) alloy were immersed for 372 days under static, non-refreshed conditions in media initially prepared to represent normal, inflammatory, and severe inflammatory environments. After exposure, the specimens were removed, rinsed, and evaluated by open-circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy in freshly prepared solutions of the corresponding nominal compositions. The original immersion solutions were analyzed by inductively coupled plasma optical emission spectrometry to determine released elements. TNZS maintained the most noble electrochemical behavior, lowest corrosion current density, and highest passive-layer resistance in all media. Elemental release increased with solution aggressiveness, following the order normal < inflammatory < severe inflammatory. Ti-6Al-4V released Al and V, whereas TNZS released lower total ion concentrations and avoided potentially harmful alloying elements. Under the tested static, non-refreshed conditions, TNZS showed lower apparent corrosion current density, higher fitted passive-layer resistance, and lower filtered dissolved elemental release than CP-Ti and Ti-6Al-4V.
