Continuous flow process for preparing budesonide.
Article in Journal of flow chemistry, 2022. 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
Budesonide, a glucocorticosteroid, is used as anti-asthmatic drug that became generic in 2019. Existing preparation methods of budesonide require utilization of corrosive acids and involve expensive purification process. Thus, a new cost-effective continuous flow process for the synthesis of budesonide which belongs to the class of 16,17 acetals of pregnane core, is discussed in the present research findings. Flow reactor parameters such as flow rate, temperature, residence time, solution volumes, anti-solvents and reactor frequency are subjected to investigation on the preparation of molar ratio of budesonide epimers. Further, the suitable parameters entail for obtaining the desired molar ratio of epimers. In another aspect, particle size optimization studies are also performed to get the desired budesonide solid product. A continuous flow process for preparation of budesonide is identified from the present research investigation which can be readily transferred to industrial scale up. Graphical abstract:
