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

backgroundPerioperative bleeding and allogeneic blood transfusion are generally thought to affect the outcomes of patients. This meta-analysis aimed to determine the benefits and risks of several cardiovascular interventions in patients undergoing hepatectomy.

methodsIn this systematic review and meta-analysis, randomised controlled trials (RCTs) were searched in the Cochrane Library, Medline, Embase, and Web of Science to February 02, 2023. RCTs focused on cardiovascular interventions aimed at reducing blood loss or blood transfusion requirements during hepatectomy were included. The primary outcomes were perioperative blood loss amount, number of patients requiring allogeneic blood transfusion and overall occurrence of postoperative complications. The secondary outcomes were operating time, perioperative mortality rate, postoperative liver and kidney function and length of hospital stay.

resultsSeventeen RCTs were included in the analysis. A total of 841 patients who underwent hepatectomy in 10 trials were included in the comparative analysis between low central venous pressure (CVP) and control groups. The forest plots showed a low operative bleeding volume [(mean difference (MD): -409.75 mL, 95% confidence intervals (CI) -616.56 to -202.94, P < 0.001], reduced blood transfusion rate [risk ratio (RR): 0.47, 95% CI 0.34 to 0.65, P < 0.001], shortened operating time (MD: -13.42 min, 95% CI -22.59 to -4.26, P = 0.004), and fewer postoperative complications (RR: 0.76, 95% CI 0.58 to 0.99, P = 0.04) in the low CVP group than in the control group. Five and two trials compared the following interventions, respectively: 'acute normovolaemic haemodilution (ANH) vs control' and 'autologous blood donation vs control'. ANH and autologous blood donation could not reduce the blood loss amount but greatly decreased the number of patients requiring allogeneic blood transfusion. No benefits were found in the rate of mortality and length of postoperative hospital stay in any of the comparisons.

conclusionLowering the CVP seems to be effective and safe in adult patients undergoing hepatectomy. ANH and autologous blood donation should be used as a part of blood management for suitable patients in certain circumstances.
