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 and aim Postoperative pain following root canal treatment (RCT) can be influenced by the obturation technique, as variations in apical sealing and material extrusion may affect periapical tissue response. The aim of this study was to evaluate postoperative pain and apical outcomes following three different obturation techniques in patients diagnosed with symptomatic irreversible pulpitis, with or without apical periodontitis. Methods Seventy-five single-rooted teeth requiring RCT were randomly allocated into three groups based on the obturation technique used: cold lateral condensation, warm vertical compaction, and carrier-based obturation (CBO). Baseline pain was recorded using a Visual Analogue Scale (VAS). All procedures were performed by a single experienced endodontist in two visits. Postoperative pain levels were recorded using the VAS at six, 24, 48, and 72 hours. The incidence of apical sealing of lateral canals and ramifications, as well as obturation material extrusion, was evaluated radiographically. Results Intergroup comparison of postoperative pain scores using the Kruskal-Wallis H test showed no statistically significant difference among the three obturation techniques at any of the evaluated time intervals (p > 0.05). The CBO group demonstrated a higher incidence of sealing of apical ramifications and lateral canals; however, the overall difference among groups was not statistically significant (p = 0.056). A significantly higher incidence of obturation material extrusion was observed in the CBO group (p = 0.020). Conclusions The obturation technique did not significantly affect postoperative pain. The CBO method demonstrated a higher incidence of apical sealing but was associated with increased material extrusion. The selection of the obturation technique should balance sealing efficacy with the risk of extrusion.
