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 The electric pulp tester (EPT) is an extensively used diagnostic tool in endodontics. However, several factors, especially the location and thickness of the tooth structures, such as enamel and dentine, can affect the result of an electric pulp test. Further, these factors also alter the pain threshold, which may lead to an inaccurate diagnosis. Hence, it is crucial to ascertain the optimal tooth surface that requires minimal time to elicit a response and pain threshold to enhance the effectiveness of the electric pulp tester for diagnosing the status of the pulp. Methods Fifty volunteers (36 males and 14 females) aged 18 to 32 years without any prior experience with the EPT were recruited. The EPT was placed on the seven premolar sites, and molar teeth with an appropriate electrolyte as a conducting medium were tested. The pain threshold values were recorded using the stopwatch, whereas pain assessment was carried out using the Memojis pain scale. An independent sample t-test and descriptive statistics were used to analyze the data statistically. Results The buccal occlusal third in males (27.3±8.6 seconds) and the buccal middle third in females (28.5±8.2 seconds) showed lower response times than other sites in premolar teeth. The mesiobuccal cusp showed a lower response time for males (21.3±6.6 seconds) and females (21.5±6.2 seconds) in molar teeth. Of all the various sites tested, the majority of the individuals chose pain scores of 0 (36 in premolars, 84 in molars), two (138 in premolars, 180 in molars), and four (96 in premolars, 42 in molars) in both the premolars and molars. Conclusion The ideal sites for placing the EPT in premolars for males and females are the buccal occlusal third and the buccal middle third. At the same time, the mesiobuccal cusp is the ideal site for molars in both males and females, as it is responded to the quickest by the electric current. Most individuals have experienced a score of two (hurts a little bit) for the perceived pain using EPT for both the molars and premolars.
