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 conventional procedure using stainless steel hand files is very time-consuming and has associated disadvantages. A literature review demonstrates the effectiveness of nickel-titanium (Ni-Ti) rotary files in this regard. Technological advancements have led to the development of various single-file Ni-Ti rotary systems, such as Kedo-S and XP-Endo Shaper. Aim: To compare the instrumentation time and quality of obturation in primary molars, assessed by the Coll and Sadrian criteria, using two single-file Ni-Ti rotary systems, Kedo-S and XP-Endo Shaper. Materials and methods: A randomized clinical trial was conducted in children aged 4-9 years requiring single- or two-visit pulpectomy. A total of 50 primary molars were allocated into two groups of 25 each, that is, group I (Kedo-S) and group II (XP-Endo Shaper). Instrumentation time was recorded using a digital stopwatch, while the quality of obturation was assessed radiographically using the Coll and Sadrian criteria. The obtained data were subjected to statistical analysis using the Mann-Whitney Results: XP-Endo Shaper demonstrated a statistically significant difference in instrumentation time ( Conclusion: The use of the adaptive XP-Endo Shaper resulted in reduced instrumentation time and better quality of obturation. Clinical significance: Pulpectomies performed under general anesthesia, where time is a constraint, can benefit from the use of single-file rotary systems. Considering the quality of obturation, XP-Endo Shaper performed better, with fewer voids and a greater number of optimal fills due to its adaptive technology. CTRI Reg No: CTRI/2025/04/084040.
