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

backgroundProspective studies examining the changes in resting energy expenditure, metabolic adaptation (MA), and body composition following sleeve gastrectomy (SG) are limited, especially among minority populations.

methodsData were included from a secondary analysis of participants (n = 24; mean ± SD: 42 ± 11 y, 62.5% Female, 58.3% Hispanic, 20.8% non-Hispanic White, 37.5% with type 2 diabetes not on insulin, BMI, 41.9 ± 4.7 kg/m2) undergoing SG from a 24-month prospective study. REE was measured using indirect calorimetry at baseline, 1.5, and 6 months. Body composition (fat mass [FM] and fat-free mass [FFM]) was measured via bioelectrical impedance analysis at baseline, 1.5, 6, 12, and 24 months. Metabolic Adaptation (MA) was calculated by subtracting measured REE from predicted REE using a linear model that included FFM.

resultsREE significantly decreased from baseline to 1.5 months (-371.8 kcal/day, 95%CI: -577.5 to -166.1, p = 0.0005) and 6 months (-374.2 kcal/day, 95%CI: -647.3 to -101.0, p = 0.006), but was not significantly different from 1.5 to 6 months (p = 0.99). MA was − 328.8 kcal/day (95%CI: -480.6 to -128.9, p = 0.008) and − 306.7 kcal/day (95%CI: -553.9 to -59.4, p = 0.02) at 1.5 and 6 months, but was not significantly different from 1.5 to 6 months (p = 0.97). REE and MA at 1.5 and 6 months were not associated with FM or FFM at 12- and 24-months following SG.

conclusionThe acute changes in REE and MA did not blunt weight loss and were not associated with body composition at 12 and 24 months; however, our findings should be interpreted with caution, given the small sample size and potential inaccuracies in body composition measurements.
