Effects of estrogen and testosterone on resting energy expenditure in older men.
Trial report in Obesity (Silver Spring, Md.), 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
The mechanisms by which sex hormones cause changes in body composition are unclear. Sex steroid deficiency might directly reduce energy expenditure/fat oxidation and thereby predispose to increased body fat. Alternatively, sex steroid deficiency could result in lean tissue loss and thus reduced energy expenditure. Our objective was to examine the independent and combined effects of acute testosterone and estrogen withdrawal on respiratory exchange ratio (RER) and resting energy expenditure (REE) in men. The objective of the study was to examine the independent and combined effects of acute estrogen and testosterone withdrawal on RER and REE in men. A total of 54 men aged 50-80 years, BMI range of 17-35 kg/m(2) underwent a 3-week eugonadal run-in hormone-treatment period involving suppression of endogenous sex steroids using letrozole and leuprolide acetate (Lupron) while sex steroid concentrations were maintained with transdermal testosterone (T) and estradiol (E). A second Lupron injection was then given and participants were randomized to one of the following four 3-week treatment groups: group A (-T, -E), group B (-T, +E), group C (+T, -E), and group D (+T, +E). REE and RER were measured via indirect calorimetry before and after the 3-week treatment period. Three-week suppression and/or repletion of estrogen or testosterone did not produce changes in RER or REE within or between groups. We conclude that abrupt changes in sex steroids does not change resting substrate oxidation, indicating that changes that can be observed after more prolonged periods of deficiency are most likely due to direct effects of sex steroids on body composition.
