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
objectiveIn obesity, the fat storage in the body increases excessively and affects the whole metabolism.
methodsSixty-two obese patients were included in the study. The effect of weight loss, which was achieved with a 3-month diet/exercise program, on the following analytes was investigated; serum total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, triacylglycerol, triglycerides (TAG), glucose, resistin, apelin, and a transcription factor sterol regulatory element binding protein-1c, and blood hemoglobin A1c. Basal (prediet/exercise) levels of analytes were taken as control values, and they were compared to the postdiet/exercise levels.
resultsAfter the 3-month diet/exercise program, apelin, hemoglobin A1c, and triacylglycerol, triglycerides levels decreased compared to basal levels, and those of sterol regulatory element binding protein-1c, glucose, and low-density lipoprotein-cholesterol increased.
conclusionConsidering the insulin-like effects of apelin, high levels of apelin in prediet/exercise phase can be interpreted as a kind of resistance to apelin, and the decreased postdiet/exercise apelin levels as a kind of normalization of it. The decrease in hemoglobin A1c and triacylglycerol, triglycerides levels following weight loss can be appreciated. High basal serum sterol regulatory element binding protein-1c levels suggest an increase in lipogenesis. The increases in glucose and low-density lipoprotein-cholesterol after diet/exercise program remain in a physiological range. However, we think that a longer diet/exercise follow-up in a larger population will further elaborate on the issue.
