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

backgroundObstructive sleep apnea (OSA) is very frequent and often unrecognized in surgical patients. OSA is associated with perioperative complications. We evaluated the effects of OSA on postoperative complications and hospital outcomes in patients undergoing coronary artery bypass graft (CABG) surgery.

methodsCandidates of elective CABG were evaluated by the Berlin questionnaire for OSA. After surgery, patients were assessed for postoperative complications, re-admission to the Intensive Care Unit (ICU), duration of intubation, re-intubation, days spent in the ICU and the hospital.

resultsWe studied 61 patients who underwent CABG from which 25 (40.9%) patients had OSA. Patients with OSA had higher body mass index (29.5 ± 3.9 vs. 26.0 ± 3.7 kg/m(2), P = 0.003) and higher frequency of hypertension (68.0% vs. 30.5%, P = 0.003), dyslipidemia (36.0% vs. 5.5%, P = 0.004), and pulmonary disease (16.0 vs. 2.7%, P = 0.08). Regarding the surgical outcomes, OSA patients had longer intubation duration (0.75 ± 0.60 vs. 0.41 ± 0.56 days, P = 0.03).

conclusionsObstructive sleep apnea is frequent, but unrecognized among patients undergoing CABG. In these patients, OSA is associated with prolonged intubation duration. Preventing these problems may be possible by early diagnosis and management of OSA in cardiac surgery patients. Further studies with larger sample of patients and longer follow-ups are required in this regard.
