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
unlabelledThis study evaluated the hypothesis that increased bone marrow adipogenesis is coupled to decreased bone formation in rats consuming alcohol. Parathyroid hormone (PTH) increased bone formation but had no effect on marrow adiposity. We conclude that increased adiposity does not prevent the bone anabolic response to PTH.
introductionAlcoholism results in decreased bone formation and increased bone marrow adiposity. The present study tested the hypothesis that these reciprocal changes are coupled by evaluating the effect of intermittent PTH on bone formation and bone marrow adiposity in a rat model for chronic alcohol abuse.
methodsThree-month-old male Sprague Dawley rats (n = 10-11/group) were fed the Lieber-DeCarli liquid diet with 35% of the calories derived from ethanol. Control rats were pair-fed an isocaloric alcohol-free diet. The rats were administered low dose PTH (1 µg/kg/day sc, 5 d/week) or vehicle for 6 weeks. Cancellous bone architecture in lumbar vertebrae was evaluated by micro-computed tomography followed by histomorphometric assessment of bone formation and marrow adiposity.
resultsAlcohol increased bone marrow adiposity but reduced bone formation. The latter was due to decreases in mineralizing perimeter/bone perimeter, a surrogate measure of osteoblast number, and mineral apposition rate, a measure of osteoblast activity. PTH increased bone formation by increasing mineralizing perimeter/bone perimeter. In contrast, PTH had no effect on mineral apposition rate or bone marrow adiposity. Interactions between alcohol consumption and PTH treatment were not detected for any endpoints evaluated.
conclusionsPTH treatment blunted the decrease in mineralizing perimeter/bone perimeter in alcohol-fed rats but was ineffective in preventing the increase in bone marrow adiposity. These findings suggest that the alcohol-induced increase in adipocytes is not directly responsible for the accompanying reduction in bone formation.
