1 · What the graph read from it

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.

2 · The registry

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

objectivesThis study evaluated surgical temperature, accuracy, and efficiency in endodontic microsurgery (EMS) using the sleeveless guided system. MATERIALS AND

methodsSleeveless and sleeve guided systems were fabricated. Thermocouples were used to measure temperature changes during guided preparation in models (n = 5) featuring bone blocks installed in anterior, premolar, and molar regions. 72 teeth in 6 EMS models used for simulating the clinical scenario of endodontic microsurgery were equally randomized into 6 groups by guide type (sleeveless/sleeve/freehand) and operator experience, with each group containing matched dentition (2 anterior/2 premolar/2 molar teeth per arch; n = 12). Preoperative and postoperative models were superimposed using 3-matic Medical evaluate preparation accuracy, with surgical duration compared for efficiency. Temperature data were analyzed via t-test; accuracy and efficiency were assessed using two-way ANOVA.

resultsThe sleeveless guided system demonstrated significantly lower surgical area temperatures than the sleeve guided system (P < 0.001). Compared to freehand, it reduced three-dimensional (3D) deviation by 1.14 mm (52.8%), angular deviation by 4.06° (49.6%), and surgical time by 40.5 s (P < 0.05). When using sleeveless system, experienced operators exhibited reductions of 0.65 mm in 3D deviation and 4.51° in angular deviation, whereas inexperienced operators demonstrated larger reductions of 1.96 mm and 5.79° respectively. No significant differences were observed between guide systems in accuracy or efficiency (P > 0.05).

conclusionThe sleeveless guided system effectively reduces heat generation and enhances surgical accuracy and efficiency compared to freehand techniques significantly, with performance comparable to the sleeve guided system. CLINICAL RELEVANCE: The sleeveless guided system demonstrates promising applications in EMS.
