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

objectivesWe investigated whether (1) subcutaneous adipose tissue (SAT) mitochondrial capacity predicts weight loss success and (2) weight loss ameliorates obesity-related SAT mitochondrial abnormalities.

methodsSAT biopsies were obtained from 19 clinically healthy obese subjects (body mass index (BMI) 34.6±2.7 kg m

resultsDespite similar baseline clinical characteristics, SAT in the WL group exhibited higher gene expression level of nuclear-encoded mitochondrial pathways (P=0.0224 OXPHOS, P=0.0086 tricarboxylic acid cycle, P=0.0074 fatty acid beta-oxidation and P=0.0122 BCAA), mtDNA transcript COX1 (P=0.0229) and protein level of Porin (P=0.0462) than the WR group. Many baseline mitochondrial parameters correlated with WL success, and with SAT and VAT glucose uptake. During WL, the nuclear-encoded mitochondrial pathways were downregulated, together with increased plasma metabolite levels of BCAAs in both groups. MtDNA copy number increased in the WR group at 5 months (P=0.012), but decreased to baseline level between 5 and 12 months (P=0.015). The only significant change in the WL group for mtDNA was a reduction between 5 and 12 months (P=0.004). The levels of Porin did not change in either group upon WL.

conclusionsHigher mitochondrial capacity in SAT predicts good long-term WL success. WL does not ameliorate SAT mitochondrial downregulation and based on pathway expression, may paradoxically further reduce it.Data availability:The transcriptomics data generated in this study have been deposited to the Gene Expression Omnibus public repository, accession number GSE103769.
