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.

Abstract

objectivesA case-control study was undertaken to assess the impact of preoperative nutrition on surgical outcomes in patients with inflammatory bowel disease with vs without preoperative biologic therapy.

methodsSeventy patients who had received biologic therapy within 8 weeks before undergoing resection for active ulcerative colitis (n = 34) or Crohn's disease (n = 36) were included (BIO group). The control group comprised 70 patients without exposure to biologics, selected based on 5 matching criteria: inflammatory bowel disease subtype (ulcerative colitis/Crohn's disease), age (≤ or >40 years), disease severity (moderate/severe), surgical approach (open/laparoscopic), and main surgical procedure. Poor nutrition was defined as the presence of at least one of the following criteria: weight loss >10%-15% within 6 months, body mass index <18.5 kg/m, Subjective Global Assessment Grade C, or serum albumin <30 g/L.

resultsThe proportion of patients with preoperative poor nutrition was 43% in the BIO and 33% in the control groups (P = 0.22). The incidence of postoperative infectious complications (anastomotic leak, intra-abdominal abscess, enterocutaneous fistula, or wound infection) was 16% in the BIO and 14% in the control groups (P = 0.81). In the BIO group, poor nutrition significantly increased the risk of infectious complications (27% vs 8% without poor nutrition, P = 0.03). In addition, in the control group, the incidence of infectious complications was higher in patients with poor nutrition, but not significantly (22% vs 11%, P = 0.21). DISCUSSION: Poor nutrition increases the risk of infectious complications after surgery. The detrimental effects of poor nutrition on postsurgical infection may be enhanced in patients who have received biologic therapy preoperatively.
