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

backgroundTo examine changes in sex hormones after laparoscopic sleeve gastrectomy (LSG) in Chinese obese male patients and their correlation with metabolic parameters including serum uric acid (SUA)

methodsA total of 56 obese men with body mass index (BMI) 41.9 ± 5.8 kg/m

resultsAt baseline, low TT and hyperuricemia (HUA) were common in obese men. Twelve months after LSG, statistically significant reduction in weight, BMI, and glucolipid metabolism indices was noted. SUA levels declined remarkably from 474.9 ± 94.6 to 338.8 ± 81.9 μmol/L and the percentage of HUA decreased from 76.8 to 54.1% (all P < 0.001). Additionally, significant increases in TT, SHBG, and cFT as well as a decrease in percentage of low TT were observed after LSG (all P < 0.05), while E2, FSH, and LH did not change significantly. Moreover, changes in TT levels were more pronounced than those of other sex hormones. After age and BMI were adjusted, increased TT levels were correlated significantly with decreased SUA (β = - 1.077, P < 0.05), BMI (β = - 0.712, P < 0.001), and HOMA-IR (β = - 0.652, P < 0.05), as well as increased SHBG (β = 0.759, P < 0.001).

conclusionsLSG promotes a significant increase in TT levels in Chinese obese men, which may be mediated by substantial weight loss, SUA reduction, and improved insulin resistance (IR).
