Removal of active pharmaceutical compounds in Primalan and Diane using pumpkin biochar: synthesis, characterization, and adsorption study.
Article in RSC advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This investigation aims to apply the adsorption process to eliminate mequitazine and ethinylestradiol, the active molecules of Primalan and Diane, respectively, from aqueous solutions, utilizing biochar synthesized from pumpkin fruits (PB-500). The results revealed that the obtained adsorbent possessed a notable specific surface area, contributing to removal efficiencies of 66.61% and 62.37% for mequitazine and ethinylestradiol, respectively. The sludge recovered under equilibrium conditions was also characterized to facilitate comparison of biochar properties before and after adsorption. Several models were employed to analyze the adsorption kinetics and isotherms, showing that the pseudo-second-order model offers the optimal representation for the kinetic behavior. Both the Sips and Freundlich models accurately described the isotherm data. On the other hand, the adsorption on PB-500 was clearly affected by the variation in solution pH. The PB-500 variation test indicated that the optimum adsorbent concentration was around 0.8 g L
