External proficiency testing improves inter-scorer reliability of polysomnography scoring.

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
purposeThis study evaluated whether or not polysomnography (PSG) inter-scorer reliability (ISR) across sleep centres could be improved by external proficiency testing (EPT), or by EPT combined with method alignment training.
methodsExperienced scorers form 15 sleep centres were randomised to the following: (1) a control group, (2) a group that received a self-directed intervention of EPT reports (EPT
resultsAmong 30 scorers, there were no ISR changes in controls between baseline (BL) and 6 months (6 m). Both EPT groups showed ISR improvement from BL to 6 m for respiratory, arousal and sleep scoring (p < 0.05). Respiratory scoring back-transformed mean (95CI) proportion of specific agreement (PSA) for the EPT
conclusionExternal proficiency testing produced modest, statistically significant PSG inter-scorer reliability improvements among experienced scorers across sleep centres, with potential to improve clinical management of individual patients and increase research study statistical power.
