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

backgroundHepatic portal venous gas (HPVG) is rare but potentially serious condition. Main cause of HPVG is bowel ischemia, while detection of HPVG without bowel ischemia may have been increasing possibly due to widespread use of computed tomography. However, little is known about variation in etiologies of HPVG and mortality of HPVG with each etiology. We examined patient backgrounds, underlying diseases, and in-hospital mortality of HPVG patients using a national inpatient database.

methodsUsing the Diagnosis Procedure Combination database in Japan, we identified inpatients diagnosed with HPVG from July 1, 2010 to March 31, 2015. Patients' data included age, sex, comorbidities at admission, complications after admission, body mass index, surgical procedures, medications, and discharge status. In-hospital mortality was compared between the subgroups divided by the patient backgrounds and underlying diseases.

resultsA total of 1590 patients were identified during the study period. The mean age was 79.3 years old and the proportion of bowel ischemia was 53%. The overall in-hospital mortality was 27.3%. In-hospital mortality of HPVG with bowel ischemia, gastrointestinal tract (GIT) obstruction or dilation, GIT perforation, GIT infection, or sepsis was 26.8, 31.1, 33.3, 13.6, or 56.4%, respectively. Among patients with bowel ischemia, 32.2% patients received operation and their in-hospital mortality was 16.5%.

conclusionsHPVG patients in the present study were relatively older but less likely to die than those in previous studies. Attention should be paid to the fact that mortality of HPVG without bowel ischemia was not always lower compared to that with bowel ischemia.
