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

To explore the relationship between the serum vascular endothelial growth factor (VEGF) level and the severity of obstructive sleep apnea hypopnea syndrome (OSAHS), the concentrations of serum VEGF in 40 OSAHS patients and 9 healthy controls were measured by using ELISA method. Meanwhile the correlation between the concentration of VEGF and parameters of polysomnography (PSG) was examined. Our results showed that the concentrations of VEGF were significantly higher in OSAHS patients with severe hypoxia (536.8+/-334.7 pg/mL) than in those with mild hypoxia (329.2+/-174.7 pg/mL) and healthy controls (272. 8+/-211.0 pg/mL) (P<0.05 for both). The concentrations of VEGF were also significantly higher in OSAHS patients with hypertension (484.5+/-261.4 pg/mL) than in those without hypertension (311.0+/-158.4 pg/mL) and healthy controls (272. 8+/-211.0 pg/mL) (P<0.05 for both). There was a positive correlation between the concentration of VEGF and the apnea hypopnea index (AHI) (r=0.34, P<0.05). It is concluded that the concentration of the serum VEGF is positively related to the severity of OSAHS. The elevated serum VEGF level may be involved in the pathogenesis of the complications of obstructive sleep apnea hypopnea syndrome.
