Agreement test of P value versus Bayes factor for sample means comparison: analysis of articles from the Angle Orthodontist journal.
Article in BMC medical research methodology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundResearchers are cautioned against misinterpreting the conventional P value, especially while implementing the popular t test. Therefore, this study evaluated the agreement between the P value and Bayes factor (BF
methodsData pooling was undertaken using the modified PRISMA flow diagram. Per the inclusion criteria applied to The Angle Orthodontist journal for a two-year period (November 2016 to September 2018), all articles that utilised the t test for statistical analysis were selected. The agreement was evaluated between the P value and Bayes factor set at 0.05 and 1, respectively. The percentage of agreement and Kappa coefficient were calculated. Plotting of effect size against P value and BF
resultsFrom 265 articles, 82 utilised the t test. Of these, only 37 articles met the inclusion criteria. The study identified 793 justifiable t tests (438 independent-sample and 355 dependent-sample t tests) for which the agreement percentage and Kappa coefficient were found to be 93.57% and 0.87, respectively. However, when anecdotal evidence (1/3 < BF
conclusionsThe Kappa coefficient indicated perfect agreement between the two methods. BF
