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

A 75-year-old woman was hospitalized because of sudden impairment of mobility, fever, and abdominal tenderness. Abdominal ultrasonography and computed tomography revealed a tumorous mass in the left adnexa. Escherichia coli, and Bacteroides fragilis were detected in urine and blood cultures, respectively. Despite ceftriaxone therapy, the fever persisted. B. fragilis was detected in the uterine pus after separation of vulvar adhesions and uterine drainage. The symptoms persisted, despite changing to ampicillin-sulbactam. Citrobacter amalonaticus was detected in the abscess after resection of the left fallopian tube and intra-abdominal drainage. After changing to cefepime, there was no recurrence of the abscess. C. amalonaticus should be considered for patients with urinary tract abnormalities.
