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.

Abstract

objectiveFat taste sensitivity has been implicated in long-term weight loss after bariatric surgery. Unexpectedly, improvement of orosensory fat acuity was not systematic in operated patients.

methodsObesity-induced alterations of gene expression in gustatory papillae having been recently reported, we have explored the fungiform transcriptomic activity in the bariatric surgery context. Fat taste detection thresholds (three-alternative ascending forced-choice tests) alongside transcriptomic profiling of freshly isolated fungiform papillae were assessed in women with severe obesity before and 6 months after sleeve gastrectomy.

resultsAccording to evolution of post surgery detection thresholds, lipid-improved and -unimproved subgroups were identified, despite similar initial anthropometric parameters. Lower weight loss and higher plasma fasting insulin, C-reactive protein, and fibrinogen levels distinguished lipid-unimproved patients. This subgroup also overexpressed genes involved in inflammation and apoptosis, with certain ones being positively correlated with high lipid detection thresholds (low sensitivity), whereas the key gene of taste bud cell signaling, TRPM5, was down-expressed. In lipid-improved patients, genes implicated in cell renewal, neuronal function, and receptor recycling were upregulated and associated with better lipid detection efficiency. Pathway enrichment identified immune and anti-inflammatory activities in lipid-unimproved and -improved groups, respectively.

conclusionsThese findings collectively suggest that changes in gene expression within gustatory papillae contribute to fat taste sensitivity after sleeve gastrectomy.
