Characterization of Priestia megaterium S1, a polymer degrading gut microbe isolated from the gut of Tenebrio molitor larvae fed on Styrofoam.
Article in Archives of microbiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 study reveals that Tenebrio molitor larvae are fed with two different feeds i.e., barley bran along with Styrofoam, and barley bran without Styrofoam, the survival percentage of mealworms shows 86 and 89%, respectively. Five isolates namely S1, S2, S3, S4, and S5 were isolated from the gut of Styrofoam-feeding Tenebrio molitor larvae and tested for Hydrophobicity percentage, clear zone assay and turbidity measurement. S1 isolate showed best (turbidity percentage of 19.65%, 13.54% hydrophobicity percentage, and 37% zone of clearance) when compared to other isolates, respectively. 16S rRNA characterization of S1 isolate revealed that the isolate belongs to Priestia megaterium S1(ON024787). Biodegradation of PE and PS beads by Priestia megaterium S1 makes physical and structural changes over 180 days, after microbial adhesion to the beads. Growth parameters have shown that the Priestia megaterium S1 thrives more effectively in the pH (6.5), temperature (28 °C) and at 1.5% LDPE/HDPE/PS concentration there is maximum utilization of carbon and a high percentage survival rate. Significant colonization of the isolate after 30 days over beads of LDPE (52.47%), HDPE (49.26%), and PS (48.11%), respectively. Experimental data revealed that Priestia megaterium S1 have PE and PS beads degradation capacity, proven by weight loss studies, at 6th-month percentage weight loss of LDPE (36.1%), HDPE (31.9%), and PS (28.6%), the percentage loss of carbon and hydrogen shows higher when compared to control. One month Biological Oxygen Demand (BOD) showed that LDPE (7.4 mg/l), HDPE (7.2 mg/l), PS (6.7 mg/l), and simultaneous studies on CO
