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
aimTo assess the impact of 980 nm diode laser-activated irrigation with or without EDTA on the adaptability of root canal filling in oval-shaped canals using a scanning electron microscope. METHODOLOGY: Forty-five single-rooted mandibular premolars were assigned into three groups (n = 15) based on the final irrigation protocol: Conventional irrigation without activation; 980 nm diode laser without EDTA; 980 nm diode laser with EDTA. The marginal gap width (μm) and surface area (μm²) between the obturating material and the root canal were measured in the coronal, middle, and apical thirds using SEM software (ImageJ software version 1.53 t). The data was analyzed using Two-way ANOVA and Bonferroni's post hoc tests.
resultsAll groups demonstrated statistically significant differences in mean gap width and surface area (p < 0.001) at the coronal, middle and apical root sections. Diode laser with EDTA group had the lowest gap values, followed by the diode laser group, while the conventional group recorded the highest values. Diode laser group exhibited the highest gap value in the coronal section. Additionally, significant differences in mean gap width and surface area were observed at different root levels within each group (p < 0.001). The highest mean gap value observed in the apical section, whereas the lowest value was found in the middle section for both the diode laser with EDTA and diode laser groups. In contrast, the conventional group had its lowest value in the coronal section.
conclusionActivation of the 2.6% NaOCl and 17% EDTA using 980 nm diode laser improves the adaptation of the root canal filling to the canal walls.
