Comparison of post-operative pain after root canal instrumentation with hand K-files, H-files and rotary Kedo-S files in primary teeth: a randomised clinical trial.
Trial report in European archives of paediatric dentistry : official journal of the European Academy of Paediatric Dentistry, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03964766 (Postoperative Pain Following Pulpectomy of Primary Molars With Rotary Instrumentation Versus Manual Instrumentation), which is not on this map. Cited by 14 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
purposeTo compare the post-operative pain after root canal instrumentation with hand K-files, H-files and rotary Kedo-S in primary teeth.
methodAll 4-6-year-old children were invited and 69 agreed to participate. The participants were randomly divided and distributed for instrumentation with K-file (Group 1), H-file (Group 2) and rotary Kedo-S files (Group 3). After completion of root canal procedure, the post-operative pain was evaluated at intervals of 6, 12, 24, 48, and 72 h using modified Wong-Baker pain scale and compared between the groups.
resultsPost-operative pain between three groups at 6, 12, 24, 48 and 72 h was compared using Chi square test. There was decreased post-operative pain with Kedo-S rotary files as compared to other two groups (P value < 0.001). The post-operative pain decreased after 12 h for all the groups with no pain at 24, 48 and 72 h intervals.
conclusionPaediatric rotary files Kedo-S showed significantly less post-operative pain as compared to K-file and H-file at 6 h and 12 h intervals. However, follow-up interval of 24, 48 and 72 h showed no significant difference between the rotary and hand file groups.
