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
objectivesActivation of sodium hypochlorite (NaOCl) to remove biofilm from lateral canal is important for the success of endodontic treatment. This study aimed to compare the biofilm dissolving capacity of different irrigation techniques in resin blocks with two lateral canals manufactured with 3D printers. Materials and methods: Biofilm-mimicking hydrogel was placed in the upper and lower lateral canals of 75 resin blocks. Main canals of the blocks were irrigated with 5% NaOCl. Then, the blocks were randomly divided into five groups: sonic activation (SA), passive ultrasonic irrigation (PUI), intracanal heating (ICH), self-adjusting file (SAF) and control. The amount of hydrogel removed was measured by weighing the blocks before and after the treatment and further visually scored. Data were analyzed using Kruskall Wallis H, Wilcoxon, Tukey Post-hoc HSD (Honestly Significant Difference) and one-way ANOVA tests.
resultsThe SAF group showed the highest hydrogel scores compared to other groups (p < 0.05). The hydrogel dissolution capacity of the SA group was lower compared to SAF, PUI and ICH techniques (p < 0.05). Based on visual scoring, SAF group was superior to other activation methods (p < 0.05) which are similar to each other (p > 0.05) in both upper and lower lateral canals. Conclusion: All activation methods were superior than the control group. The SAF system demonstrated superior hydrogel dissolving ability, while SA, PUI, and ICH groups showed similar effectiveness.
