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 The outcome of a successful root canal treatment depends on effective debridement, shaping, and obturation of the root canal system. The process of obturation is a requisite for ensuring to provide a hermetic seal in order to prevent microbial re-infection. Among the various existing techniques, the single-cone technique, warm vertical compaction, and thermoplasticized gutta-percha are notably the most popular techniques used in endodontic procedures. While assessment of obturating techniques has hugely relied on 2D radio-imaging in the past, it has its limitations, such as distortion of image, superimposition. Therefore, this study was conducted to assess the efficacy of the three different obturating techniques using three 3D techniques of cone beam computed tomography (CBCT). The findings will aid clinicians for long-term, successful outcomes for root canal therapies. Method The current in vitro study evaluated the efficacy of three obturation techniques - single-cone, warm vertical compaction, and thermoplasticized gutta-percha - in 72 extracted human premolars with single canals. The teeth samples were disinfected, decoronated, and instrumented using Neo Endo rotary files. After random allocation (n=24 per group), canals were obturated using one of the three techniques. Specimens were scanned via CBCT and analyzed for adaptation, voids, and density in apical, middle, and coronal thirds by two blinded observers. Data were analyzed using one-way ANOVA and Bonferroni post hoc tests (α=0.05). Results The thermoplasticized technique showed significantly superior performance with 100%, 75%, and 75% void-free cases at apical, middle, and coronal levels, respectively (mean values: 0.10-0.20). Warm vertical compaction demonstrated moderate results (75% to 62.5% void-free), while the single-cone technique showed the highest void formation (50% to 37.5% void-free). Statistical analysis revealed highly significant differences between techniques (p=0.00). Conclusion The thermoplasticized gutta-percha technique produced the most consistent results with minimal voids, making it the most effective obturation method as compared to single-cone and warm vertical compaction.
