Radiographic evaluation of narrow-diameter implants from different systems for two years.

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
Background: Narrow-diameter implants (NDIs) offer a viable alternative to bone augmentation in sites with limited alveolar ridge width. This study aimed to retrospectively evaluate the radiographic marginal bone loss (MBL) and survival rate of NDIs from three different systems after 2 years of functional loading. Methods: In this retrospective study, a total of 109 NDIs from three brands (30 Straumann Results: The overall 2-year implant survival rate was 98.17%. Two implants failed within the first 6 months. The mean MBL at 24 months was 1.67 ± 0.66 mm. Straumann Conclusion: Within the limitations of this study, NDIs demonstrated a high 2-year survival rate, supporting their use in anatomically restricted sites. The implant system, particularly the material and design, significantly influenced MBL. The TiZr alloy implant system was associated with the least bone loss. Patient- and site-specific factors, such as gender and posterior location, were also associated with greater MBL in the early healing phase, highlighting the multifactorial nature of peri-implant bone preservation.
