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

Municipal solid waste (MSW), together with other biomass resources, presents a viable feedstock for renewable energy production; however, its direct conversion is limited by high moisture content, ash content, and heterogeneous composition. These challenges can be mitigated through torrefaction, provided that suitable feedstock selection and optimization are achieved. This study investigates the physicochemical and thermal characteristics of MSW, coffee husks (CH), corn cobs (CC), and their blends to demonstrate how biomass quality can be improved through blending. MSW was blended with CH or CC at mass ratios of 25:75, 50:50, and 75:25 (db/db%). Proximate, ultimate, lignocellulosic, thermogravimetric, and calorific value analyses were conducted. Proximate analysis showed that MSW had the highest moisture (10.102 ± 0.141%), volatile matter (71.115 ± 0.759%), and ash content (6.674 ± 0.477%), whereas CH exhibited the highest fixed carbon content (18.863 ± 0.572%). Ultimate analysis revealed that MSW contained the highest hydrogen content (6.911 ± 0.183%), CH had the highest carbon content (50.001 ± 0.184%), and CC showed the highest oxygen (44.185 ± 0.273%), nitrogen (1.395 ± 0.045%), and sulfur (0.057 ± 0.035%) contents. MSW had the lowest hemicellulose (11.941 ± 0.269%) and cellulose (19.334 ± 0.294%) contents, while CC had the lowest lignin content (12.304 ± 0.219%). The calorific value of MSW (17.01 ± 0.292 MJ kg
