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 Dental fear and anxiety (DFA) are a common challenge in pediatric dentistry, often triggered by fear of pain, unfamiliar instruments, or appearance of dental instruments and injections. This fear significantly affects children's cooperation during procedures, making local anesthesia (LA) particularly anxiety-inducing. Objective This study aimed to evaluate children's level of cooperation during dental procedures in relation to their preference for different types of dental injectors. Materials and methods This study involved 150 children randomly assigned into two equal groups using a lottery method. Group A was given a choice between a metal injector and a plastic injector without stickers on it, while Group B chose a metal injector or a plastic injector with stickers around it. Children's preferences were recorded, and their behavior was assessed using the Frankl behavior rating scale during LA administration. Results In Group A, 43 (57.3%) children chose plastic injectors without stickers compared to 32 (42.7%) preferring the metal injector. In Group B, 62 (82.7%) children preferred plastic injectors with stickers, whereas only 13 (17.3%) chose metal injectors. Behavioral assessments revealed that children in Group A who preferred the plastic injector without stickers exhibited more positive behavior (n = 29, 67.5%), whereas those who preferred the metal injector showed more negative behavior (n = 10, 31.3%). In Group B, children who preferred plastic injectors with stickers showed more positive behavior (n = 43, 69.3%) when compared with those who chose metal injectors in the same group. Across all age groups, children showed more positive behavior toward plastic injectors, particularly those with stickers on them. This difference was statistically significant in the 4-6 and 7-10 years groups (p = 0.039 and p = 0.011, respectively). Conclusion The addition of stickers to plastic injectors significantly improved children's comfort and behavior during dental procedures, particularly in younger children. Older children preferred injectors without stickers, suggesting that age-specific designs enhance cooperation levels and reduce dental anxiety.
