Comparison of the P300 between maintenance and manipulation conditions in the auditory N-back paradigm among early and late adolescents.

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
purposeThe P300 recorded using N-back tasks could be used to identify brain regions involved in the maintenance and manipulation demands of working memory. The difference in brain activity between zero-back and one-back conditions highlights areas activated during the maintenance phase of the working memory. Similarly, the difference between one-back and two-back conditions reveals brain regions engaged in the manipulation process of working memory. The difference between zero-back and two-back conditions reflects areas activated during both the maintenance and manipulation processes. This study aims to compare the P300 between early and late adolescents in elicited using various N back conditions.
methodsA total of 48 individuals participated in the study in two groups. Group 1 included 24 late adolescents and group 2 included 24 early adolescents. All participants had hearing sensitivity within normal limits in both ears. The P300 was elicited by presenting stimuli using N-back paradigm in zero-back, one-back, and two-back conditions.
resultsThe latency of P300 was shorter and amplitude was larger in late adolescents compared to early adolescents. Further, the amplitude of P300 in maintenance process was highest compared to the manipulation process at all the electrode sites. However, this difference was not statistically significant between groups across conditions.
conclusionThe present study shows that the P300 amplitude is not significantly different between early and late adolescents across the N-back conditions.
