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

backgroundGastrojejunostomy (GJJ) and endoscopic stenting (ES) are palliative treatments for gastric outlet obstruction (GOO) caused by gastric cancer. We compared the outcomes of GJJ with ES by performing a meta-analysis.

methodsClinical trials that compared GJJ with ES for the treatment of GOO in gastric cancer were included in the meta-analysis. Procedure time, time to resumption of oral intake, duration of hospital stay, patency duration, and overall survival days were compared using weighted mean differences (WMDs). Technical success, clinical success, procedure-related mortality, complications, the rate of re-obstruction, postoperative chemotherapy, and reintervention were compared using odds ratios (OR s).

resultsNine studies were included in the analysis. Technical success and clinical success were not significantly different between the ES and GJJ groups. The ES group had a shorter procedure time (WMD = -80.89 min, 95% confidence interval [CI] = -93.99 to -67.78,P < 0.001), faster resumption of oral intake (WMD = -3.45 days, 95% CI = -5.25 to -1.65,P < 0.001), and shorter duration of hospital stay (WMD = -7.67 days, 95% CI = -11.02 to -4.33,P < 0.001). The rate of minor complications was significantly higher in the GJJ group (OR = 0.13, 95% CI = 0.04-0.40,P < 0.001). However, the rates of major complications (OR = 6.91, 95% CI = 3.90-12.25,P < 0.001), re-obstruction (OR= 7.75, 95% CI = 4.06-14.78,P < 0.001), and reintervention (OR= 6.27, 95% CI = 3.36-11.68,P < 0.001) were significantly lower in the GJJ group than that in the ES group. Moreover, GJJ was significantly associated with a longer patency duration (WMD = -167.16 days, 95% CI = -254.01 to -89.31,P < 0.001) and overall survival (WMD = -103.20 days, 95% CI = -161.49 to -44.91, P= 0.001).

conclusionsBoth GJJ and ES are effective procedures for the treatment of GOO caused by gastric cancer. ES is associated with better short-term outcomes. GJJ is preferable to ES in terms of its lower rate of stent-related complications, re-obstruction, and reintervention. GJJ should be considered a treatment option for patients with a long life expectancy and good performance status.
