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

This report describes the laparoscopic resection of a rectal GIST after treatment with imatinib mesylate. A 56-year-old male presented with a submucosal tumor (longest diameter, 8 cm) arising in the lower rectum. A core needle biopsy revealed that the tumor contained bundles of spindle-like cells. Immunostaining revealed that the tumor was positive for c-kit and CD34. Analysis of the c-kit gene revealed a substitution of ACA (threonine) by GCA (alanine) at codon 574 of exon 11. Imatinib mesylate (400 mg/day) was given as preoperative adjuvant therapy for 3 months, and the tumor shrank to 5 cm in diameter. Proctectomy with transanal anastomosis could be performed laparoscopically, while preserving the anus. There was no evidence of recurrence 2 years 6 months after surgery. Preoperative adjuvant chemotherapy with imatinib mesylate may permit the use of less invasive treatment procedures, allowing anal preservation.
