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

backgroundGastrectomy remains a major operation with potential for significant deterioration in patients' health-related quality of life (QOL). This study assessed differences in QOL among patients after distal (DG), proximal (PG), or total (TG) gastrectomy.

methodsWe prospectively enrolled patients undergoing gastrectomy at our institution between 2002 and 2007. Participants completed the European Organization for Research and Treatment of Cancer cancer (QLQ-C30) and gastric (QLQ-STO22) questionnaires preoperatively and at 5 postoperative intervals up to 18 months. We compared changes from baseline in patients based on extent of resection (proximal, distal, or total) using generalized linear models, adjusting for age, stage of disease, and (neo)adjuvant therapy. We converted QOL raw scores to reflect the proportion of patients with clinically significant deterioration based on the minimal important difference.

resultsWe included 134 patients: 82 DG, 16 PG, and 36 TG. In the immediate postoperative period, 55% of patients suffered significant impairment in their global QOL. This improved in most patients by 6 months, although 20% to 35% continued to have substantially worse QOL than before surgery. Patients who underwent PG suffered from significantly more clinical reflux [70% vs 35% (DG), 40% (TG)], nausea/vomiting (60% vs 25%, 30%), and global QOL impairment (60% vs 30%, 30%) than patients who underwent DG or TG, whose QOL scores were similar. These differences persisted up to 18 months postoperatively.

conclusionsSurgeons should discuss expectations of QOL impairment with their patients before gastrectomy and reassure them that most symptoms resolve by 6 months after operation. Patients who undergo PG suffer from worse QOL impairment than patients who undergo DG or TG.
