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

purposeThe aim of this study is to investigate possible factors influencing glomerular filtration rate (GFR) in obstructive sleep apnea (OSA).

methodsData of OSA patients admitted to Gaziantep University sleep clinic from January 2005 to January 2010 were retrospectively evaluated. GFR is calculated with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Patients younger than 18 years old were excluded.

resultsThe mean age of OSA (n = 634) and control group (n = 62) were 51.13 ± 11.61 and 50.69 ± 13.88 years, respectively (p = 0.81). The mean estimated GFR (eGFR) was 90.73 ± 19.59 ml/min/1.73 m(2) in OSA patients and 94.14 ± 18.81 ml/min/1.73 m(2) in control subjects (p = 0.19). GFR was 84.25 ± 20.87 ml/min/1.73 m(2) in patients with left ventricular hypertrophy (LVH) while it was 93.94 ± 18.44 ml/min/1.73 m(2) in patients without LVH (p = 0.00). GFR of male subjects was 92.1 ± 19.23 in OSA and 95.84 ± 20.08 ml/min/1.73 m(2) in controls (p = 0.33). GFR of female and male patients in the OSA were 87.45 ± 20.10 and 92.91 ± 18.02 ml/min/1.73 m(2), respectively (p = 0.13). Serum creatinine was higher in OSA patients compared to controls (p = 0.01). GFR was 92.30 ± 19.27 in male and 88.33 ± 19.84 ml/min/1.73 m(2) in female subjects (p = 0.01). GFR was 84.86 ± 19.95 in hypertensive patients while it was 95.11 ± 18.20 ml/min/1.73 m(2) in normotensive subjects (p = 0.00). GFR was 89.30 ± 19.96 in patients with metabolic syndrome (MetS) and it was 93.46 ± 18.68 ml/min/1.73 m(2) in patients without MetS (p = 0.00).

conclusionsGFR values were lower in sleep apneic patients with MetS as well as in patients with hypertension and LVH.
