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

purposeWe aimed to reveal whether static and dynamic pupillary responses can be used for the detection of autonomic nervous system (ANS) dysfunction in patients with obstructive sleep apnea syndrome (OSAS).

methodsWe included in this study patients with OSAS, who were divided into three groups according to the apnea-hypopnea index (AHI) (group 1, mild [n = 20]; group 2, moderate [n = 20]; and group 3, severe [n = 20]), and healthy controls (group 4, n = 20). Pupillary responses were measured using a pupillometry system.

resultsStatic (mesopic PD, P = 0.0019; low photopic PD, P = 0.001) and dynamic pupil responses (resting diameter, P = 0.004; amplitude of pupil contraction, P < 0.001; duration of pupil contraction, P = 0.022; velocity of pupil contraction, P = 0.001; and velocity of pupil dilation, P = 0.012) were affected in patients with different OSAS severities. Also, AHI was negatively correlated with mesopic PD (P = 0.008), low photopic PD (P = 0.003), resting diameter (P = 0.001), amplitude of pupil contraction (P < 0.001), duration of pupil contraction (P = 0.011), velocity of pupil contraction (P < 0.001), and velocity of pupil dilation (P = 0.001).

conclusionWe detected pupil responses innervated by the ANS were affected in the OSAS patients. This effect was more significant in the severe OSAS patients. Therefore, the pupillometry system can be an easily applicable, noninvasive method to detect ANS dysfunction in the OSA patients.
