Hepatic surface grooves in Trinidad and Tobago.

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
purposeHepatic surface grooves (HSGs) are prominent depressions on the antero-superior surface of the liver. We sought to document the prevalence of HSGs in an Eastern Caribbean population.
methodsWe observed all consecutive autopsies performed at a facility in Trinidad and Tobago and recorded the presence, number, location, width, length and depth of any HSG identified. Each liver was then sectioned to document intra-parenchymal abnormalities.
resultsSixty Autopsies were observed. There were HSGs in 9 (15%) cadavers (5 females and 4 males), at an average age of 66 years (range 48-83, Median 64, SD ± 10.4). The HSGs were located on the diaphragmatic surface of the right hemi-liver in 8 (89%) cadavers, left medial section in 4 (44%), left lateral section in 3 (33%) and coursing along Cantlie's plane in 3 (33%) cadavers. Eight (89%) cadavers with HSGs had other associated anomalies: accessory inferior grooves (5), parenchymal nutmeg changes (5), abnormal caudate morphology (4), hyperplastic left hemi-liver (3), lingular process (2), bi-lobar gallbladder (1) and/or abnormal ligamentous attachments (1).
conclusionsApproximately 15% of unselected Afro-Caribbean persons in this Eastern Caribbean population have HSGs. Every attempt should be made to identify HSGs on pre-operative imaging because they can alert the hepatobiliary surgeon to: (1) associated anatomic anomalies in 89% of cases, (2) associated hepatic congestion in 56% of persons, (3) increased risk of bleeding during liver resections and (4) increased technical complexity of liver resections. The association between HSGs, cardiovascular complications, hepatic congestion and nutmeg liver prompted us to propose a new aetiologic mechanism for HSG formation, involving localized hyperplasia at growth zones due to upregulation of beta-catenin levels.
