A Systematic Review and Meta-Analysis of Oncologic Liver Resections in Low- and Middle-Income Countries: Opportunities to Improve Evidence and Outcomes.

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
backgroundPatients in low- and middle-income countries (LMICs) are disproportionately affected by liver cancers but there is a lack of understanding of their postoperative outcomes. This study aimed to review the current status of research in LMICs regarding outcomes after oncologic hepatectomy and synthesize the data reported in the literature.
methodsThe PubMed, Scopus, Embase, Web of Science, and World Health Organization (WHO) Global Index Medicus databases were searched from database inception to May 26th, 2022. Studies that reported outcomes after oncologic hepatectomy in LMIC settings were eligible for inclusion. Two independent reviewers performed record screening and data extraction. Risk of bias assessment was performed using the National Institutes of Health Study Quality Assessment tools. Pooled results with 95% confidence intervals (95% CIs) were calculated using a random effects model.
resultsOne hundred and thirty-five studies and 16 985 patients were included. Most studies were of a "fair" quality. Two studies described pediatric patients. Only one study was from a low-income country and most African regions were not represented. The rates of major and minor complications were 11% and 27%, respectively, while 30- and 90-day mortality rates were 2% and 3% each. Postoperative liver failure (8%), surgical site infections (6%), and bile leaks (6%) were common complications.
conclusionsThis review indicates a dearth of data from LMICs on outcomes after hepatectomy, particularly from African regions and low-income countries.
