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

backgroundStandard approaches to the treatment of chronic post-radiation proctitis are associated with a high risk of complications and a high percentage of unsatisfactory results due to the reduced regenerative potential of irradiated tissues. Regenerative surgery techniques using the stromal-vascular cell fraction (SVF) based on the patient's autologous adipose tissue are a promising direction for study. CLINICAL CASE DESCRIPTION: A 76-year-old patient suffering from chronic post-radiation erosive-ulcerative proctitis, grade 4 according to RTOG-EORTC, complicated by recurrent profuse rectal bleeding, underwent local autotransplantation of SVF into the submucosal layer of the rectum and pararectal connective tissue. The follow-up colonoscopies 1 and 6 months after the surgery and histological examination showed the complete epithelialization of ulcerative defects and a decrease in proctitis activity. There were no bleeding episodes during the 12-month postoperative observation period.

conclusionThe proangiogenic, wound-healing, and anti-apoptotic effects of the SVF cell suspension provided reduction of inflammation activity, epithelialization of ulcers, and elimination of defecation-associated hemorrhage, following the SVF injection into the submucosal layer of the rectal wall and pararectal connective tissue in a patient with post-radiation proctitis with ulcers and recurrent bleeding.
