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.
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
Coffee is believed to prevent postoperative ileus. This systematic review and meta-analysis was undertaken to determine the effectiveness of coffee consumption in stimulating gastrointestinal function after abdominal surgery. A number of databases for randomized controlled trials comparing coffee consumption following abdominal surgery versus water drinking or no intervention were searched. Cochrane's Risk of Bias tool was used to assess risk of bias in included studies. Six trials involving 601 participants were included. All studies had high risk of performance bias. Three studies had an unclear risk of selection bias. Postoperative coffee consumption reduced time to first defecation (mean difference (MD), -9.98 hours; 95% CI, -16.97 to -2.99), time to first flatus (MD, -7.14 hours; 95% CI, -10.96 to -3.33), time to first bowel sound (MD, -4.17 hours; 95% CI, -7.88 to -0.47), time to tolerance of solid food (MD, -15.55 hours; 95% CI, -22.83 to -8.27), and length of hospital stay (MD, -0.74 days; 95% CI, -1.14 to -0.33). Benefits increased with increasing complexity of the procedure. None of the included studies reported adverse events associated with coffee consumption. Postoperative coffee consumption is effective and safe for enhancing the recovery of gastrointestinal function after abdominal surgery.
