The risk factors of intraoperative conversion during laparoscopic hepatectomy: a systematic review and meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
purposeIntraoperative conversion to laparotomy is a challenge during laparoscopic hepatectomy; however, the risk factors of conversion have been poorly elucidated.
methodsIn this systematic review and meta-analysis, we computed pooled odds ratios (ORs) with 95% confidence intervals (CIs) for each risk factor and evaluated heterogeneity using a L'Abbe plot, Galbraith radial plot, Cochran's Q test, and I
resultsA total of 25 eligible studies were enrolled in the meta-analysis. Higher body mass index (OR 1.346, 95% CI 1.055-1.717), hypertension (OR 1.387, 95% CI 1.100-1.749), male sex (OR 1.278, 95% CI 1.072-1.523), cirrhosis (OR 1.378, 95% CI 1.062-1.788), major resection (OR 2.041, 95% CI 1.748-2.382), posterosuperior tumor location (OR 2.420, 95% CI 1.923-3.044), and larger tumor diameter (OR 1.618, 95% CI 1.270-2.061) were found to be significantly related to intraoperative conversion during laparoscopic hepatectomy. Malignant tumor (OR 1.253, 95% CI 0.970-1.619), higher American Society of Anesthesiologists stage (OR 1.186, 95% CI 0.863-1.631), multiple tumors (OR 1.273, 95% CI 0.866-1.871), and abdominal surgery history (OR 1.236, 95% CI 0.589-2.597) were not associated with conversion. A history of abdominal surgery showed significant heterogeneity with an I
conclusionsIn this systematic review and meta-analysis, we identified a number of factors associated with intraoperative conversion during laparoscopic hepatectomy. Our findings can help patient risk evaluation to reduce the laparotomy conversion rate in laparoscopic hepatectomy.
