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
Introduction: Colour stability of composite materials is an essential property that greatly influences the longevity of dental restorations. Once in the oral cavity, dental materials must provide a stain resistance ability against environmental exposures, such as coffee. This experimental study compares the colour stability of two composite resin materials with differing nanocompositions. Objectives: Analyze the effect of coffee on the colour stability of nanohybrid composites and nanocomposites. Material and Methods: 40 composites discs were utilized in total, with 20 fabricated of an Ormocer-based nanohybrid composite (Admira Fusion) and 20 of a UDMA-based nanocomposite (Normofill nanoceram) in shade A2. 10 discs of each material were then immersed in coffee or water for 12 days. Colour measurements were taken before and after the staining period using a VITA Easyshade spectrophotometer. The colour difference (ΔE) of both composites was calculated using the CIE L*a*b* values. Results: Both Ormocer-based nanohybrid composites (Admira Fusion) and UDMA-based nanocomposites (Normo fill nanoceram) exhibited a colour change after the 12-day period. The UDMA-based nanocomposite (Normo fill nanoceram) exhibited significantly more discolouration compared to the Ormocer-based nanohybrid composite (Admira Fusion). Conclusions: Overall, there was a significant difference in colour generated by immersion in coffee as compared to water. Additionally, the Ormocer-based nanohybrid composite (Admira Fusion) exhibited significantly greater colour stability as compared to the UDMA-based nanocomposite (Normo fill nanoceram).
