Impact of postoperative mean arterial pressure on the incidence of postoperative complications after hepatic resection for primary liver malignancy.
Article in Surgery today, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeWe conducted this study to evaluate the impact of the postoperative mean arterial pressure (MAP) on surgical complications after hepatic resection.
methodsThe subjects of this study were 199 patients who underwent hepatic resection for primary liver malignancy between 2004 and 2013. A clinically relevant postoperative complication was defined as a Clavien-Dindo grade ≥ III complication.
resultsBased on an MAP cut-off value of 81.1 mmHg, the patients were grouped as follows: low MAP on both postoperative days (PODs) 1 and 2 (continuously low MAP), normal MAP on both PODs 1 and 2 (normal MAP), and others (transiently low MAP). The continuously low MAP group had the highest incidence of complications and the normal MAP group had the lowest incidence of complications compared with the expected incidence for this cohort (p < 0.01 and p = 0.01, respectively). Multivariate analysis revealed that both a continuously and transiently low MAP were independent predictors of postoperative complications (p = 0.03 and p < 0.01, respectively). Among the subtypes of complications, a low MAP had a significant relationship with ascites/pleural effusion and respiratory complications (p < 0.01 and p = 0.03, respectively).
conclusionsA low MAP on POD 1 and/or 2 is an independent predictor of postoperative complications.
