Surgical and nutritional outcomes of laparoscopic proximal gastrectomy versus total gastrectomy: a meta-analysis.

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
backgroundLaparoscopic proximal gastrectomy (LPG) is regarded as a less invasive surgery than laparoscopic total gastrectomy (LTG) for early gastric cancer located on the proximal side of the stomach. However, whether LPG is more effective than LTG remains unclear.
methodsA systematic literature search of studies assessing short-term surgical and nutritional outcomes after LPG and LTG was conducted. A meta-analysis of surgical outcomes (operative time, intraoperative estimated blood loss, postoperative complications, and length of hospital stay) and nutritional outcomes (decrease in body weight, albumin, hemoglobin, total protein, and lymphocyte count) was then performed. All of 11 papers are a retrospective cohort study.
resultsEleven studies reported assessments of the above-mentioned outcomes in 883 patients. There was a trend towards shorter operative time and lower blood loss for LPG compared to LTG though not reaching statistical significance. Other surgical outcomes showed no significant differences. Patients who underwent LTG had a significantly lower body weight (95% confidence interval, 3.01-6.05, [Formula: see text] = 4.53, p < 0.01) and hemoglobin level (95% confidence interval, 1.88-5.87, [Formula: see text] = 3.87, p < 0.01) than patients who underwent LPG at 1 year after surgery. There were no significant differences in other nutritional outcomes.
conclusionsThese results indicate LPG had some advantages in postoperative nutrition. However, no significant differences in short-term surgical outcomes were noted between the two operations. Our analysis suggests that LPG may be more beneficial compared with LTG in terms of perioperative and nutritional outcomes for early-stage gastric cancer.
