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

backgroundThere are different risk factors that affect the intensive care unit (ICU) stay after cardiac surgery.

objectivesThe aim of this study was to evaluate possible risk factors influencing prolonged ICU stay in a large referral hospital. PATIENTS AND

methodsWe conducted a case-control study to determinate causes of prolonged ICU stay in 280 adult patients undergoing cardiac surgery in a tertiary care center for cardiovascular patients, Tehran, Iran. These patients were divided into two groups according to ICU stay ≤ 96 and > 96 hours. We evaluated perioperative risk factors of ICU stay > 96 hours.

resultsAmong the 280 patients studied, 184 (65.7%) had stayed ≤ 96 hours and 96 (34.3%) had stayed > 96 hours in ICU. Frequency of prolonged ICU stay was 34.2% in patients undergoing coronary artery bypass graft (CABG), 30.8% in patients with valve surgery, and 44.8% in patients with CABG plus valve surgery. Patients with > 96 hours of ICU stay received more blood transfusion and intravenous inotropes. They also had longer anesthesia, cardiopulmonary bypass, and postoperative intubation time. There were higher incidence of postoperative tamponade, re-exploration, re-intubation, hemodialysis, and hypotension in this group (P < 0.05 for all comparisons).

conclusionsIn this study, about one-third of patients had prolonged ICU stay. Factors influencing prolonged ICU stay were medical and some non-medical factors. In the present study, up to 30% of the patients had a prolonged ICU stay of > 96 hours. Additional data from well-designed investigations are needed for further assessment of the factors influencing prolonged ICU stay after cardiac surgery.
