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

Patients with endometriosis are at a high risk of developing pelvic inflammatory disease. This case series presents three cases of colo-ovarian fistulas associated with endometriosis, highlighting the potential for conservative management in selected cases. Case 1 involved a 36-year-old woman in whom suspected communication between the colon and an endometriotic cyst was noted on computed tomography and magnetic resonance imaging (MRI). Case 2 involved a 42-year-old woman who presented with a colo-ovarian fistula on MRI. Case 3 involved another 42-year-old woman with a sigmoid colon perforation who was retrospectively diagnosed with a colo-ovarian fistula. All cases were associated with endometriosis. In Cases 1 and 2, symptoms were successfully managed conservatively. In Case 3, the colo-ovarian fistula only became apparent following hysterectomy and was treated by surgery. Although surgical intervention is commonly performed for colo-ovarian fistulas, our findings suggest that conservative treatment may be an option in select cases with endometriosis-associated fistulas.
