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

backgroundThe purpose of the study was to determine whether the active cycle of breathing technique (ACBT) has an impact on postoperative pulmonary complication (PPC) after esophagectomy.

methodsIn this prospective randomized trial, patients who were candidates for esophagectomy were randomized into groups, wherein they received either ACBT (n = 146) or conventional chest physiotherapy (control group, n = 145) on postoperative days (POD) 1-3. The primary outcome was PPC. The secondary outcomes included the incidence of anastomotic leakage (AL), efficacy of airway clearance, and postoperative hospital length of stay (LOS).

resultsAfter esophagectomy, the PPC rate was significantly lower in the ACBT group (15.2%) than in the control group (31.0%) (p = 0.001). The incidences of AL were 5.5% and 12.4% in the ACBT and control groups, respectively (p = 0.042). Mean hospital LOS was 12.3 days for the ACBT group and 16.8 days for the control group (p = 0.008). ACBT significantly increased the mean sputum wet weight (g) on POD 1-3 when compared with conventional therapy (POD 1 9.08 vs. 6.47, POD 2 16.86 vs. 10.92, POD 3 24.65 vs. 13.52, all p < 0.001). Multivariable analysis revealed that ACBT decreased the rates of PPC (odds ratio [OR] 0.403, p = 0.003), AL (OR 0.379,p = 0.038),arrhythmia (OR 0.397, p = 0.028), and bronchoscopy aspiration (OR 0.362, p = 0.016).

conclusionACBT is an effective airway clearance technique that significantly reduces the incidence of PPC after esophagectomy. ACBT could also significantly reduce both AL and LOS.
