1 · What the graph read from 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.

2 · The registry

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

backgroundIn modern office environments, maintaining adequate air quality is essential for cognitive performance and overall well-being. However, the physiological effects of ventilation (CO

methodsA crossover experiment was conducted with six office workers (mean age: 28 ± 2 years). Two conditions were compared: Condition A (with ventilation/CO

resultsA two-way mixed ANOVA revealed a significant main effect of ventilation on the LF/HF ratio during the post-nap phase (

conclusionsThese findings indicate that ventilation is a critical environmental factor influencing physiological recovery during midday naps. Optimizing air quality may enhance autonomic regulation and improve the restorative effects of short daytime sleep in office settings. These findings should be interpreted as exploratory due to the small sample size (n = 6). While LF/HF was used as an index of autonomic balance, its physiological interpretation remains debated and should be considered with caution.
