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

backgroundEarly intake after surgery can decrease postoperative ileus. Several studies show coffee can stimulate bowel activity and be safe in patients after elective colectomy, mainly due to caffeine. It was postulated that drinking Chinese green tea as rich caffeine beverage after subtotal distal gastrectomy accelerates postoperative recovery in patients.

methodThis was a single-centre parallel open-label randomized trial. Patients with gastric cancer undergoing robotic or laparoscopic subtotal gastrectomy were randomly allocated to receive drinking Chinese green tea (GT group) or potable water (PW group) after surgery. The primary endpoint was the time to gastrointestinal function recovery and tolerance of solid food, and the secondary endpoints included the incidence of postoperative complications, symptoms of postoperative adverse reaction, length of stay, pain as assessed by analgesic consumption and a visual analogue scale, and fatigue as assessed by a fatigue score model.

resultsA total of 80 patients were recruited, 40 to each group. Patient characteristics were similar in both groups. The GT group showed significantly shorter time to gastrointestinal function recovery compared with PW group to first flatus (47.23 ± 13.46 vs. 76.96 ± 20.35, P < 0.001), first bowel motion (78.70 ± 25.77 vs. 125.76 ± 36.25, P < 0.001) and tolerance of solid food (62.20 ± 16.15 vs. 98.66 ± 20.15, P < 0.001).

conclusionDrinking Chinese green tea after robotic or laparoscopic subtotal gastrectomy is safe and promotes postoperative recovery of gastrointestinal function, also was an add method with strengthening analgesia and anti-inflammatory effect in the presence of the Enhance Recovery After Surgery (ERAS) program.
