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
backgroundHuman UDP-glucuronosyltransferases (UGTs) are important membrane proteins located in endoplasmic reticulum, and play important roles in metabolism of a variety of endogenous and exogenous compounds.
aimsTo determine the influence of subtle difference in the structure of oleanolic acid and betulinic acid towards the inhibition towards the activity of UGT isoforms.
methodsIn vitro glucuronidation of 4-methylumbelliferone (4-MU) reaction was employed as the probe reaction to determine the inhibition of these two compounds towards UGTs' activity.
resultsThe inhibition of capability of oleanolic acid towards UGT1A6 and UGT1A8 were higher than betulinic acid. However, no significant difference was observed for the inhibition of oleanolic acid and betulinic acid towards UGT1A7. Furthermore, concentration-dependent behaviour was determined for the inhibition of oleanolic acid and betulinic acid towards UGT1A6 and UGT1A8. At various concentrations of oleanolic acid and betulinic acid, the inhibition of oleanolic acid towards UGT1A6 and UGT1A8 was higher than betulinic acid. CONSLUSION: Given that UGT1A6 and UGT1A8 play key role in the the inhibition of oleanolic acid towards UGT1A6 and UGT1A8 will induce drug-drug interaction and the risk of diseases.
