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

aimThe purposes of this study are to present cases of emergency surgery in which gastrointestinal perforation occurred during bevacizumab administration, consider the indications for emergency surgery, and examine the safety of scheduled surgery after a washout period for bevacizumab.

methods(a) We retrospectively investigated seven patients who underwent emergency surgery for bevacizumab-associated intestinal perforation. (b) We investigated 104 patients with advanced colorectal cancer treated with neoadjuvant therapy who underwent surgery from 2008 to 2018, retrospectively.

results(a) In the seven patients undergoing emergency surgery for gastrointestinal perforation, the median bevacizumab administration and washout periods were 16 weeks and 24 days, respectively. A stoma was created in all patients except in those who were not candidates. Two patients developed postoperative abdominal abscesses, and two patients died from perioperative sepsis and gastrointestinal bleeding, respectively; both of these patients had poor performance status. (b) In patients receiving bevacizumab (n = 45) and patients treated with bevacizumab-free regimens as neoadjuvant therapy (n = 59), 31 and 52 patients received chemoradiotherapy, respectively. We found no correlation with postoperative complications with or without bevacizumab.

conclusionThe surgical indications should be considered carefully in patients with gastrointestinal perforation secondary to bevacizumab administration. Meanwhile, after appropriate cessation time, scheduled surgery following bevacizumab administration is feasible.
