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

Bioethanol is recognized today as the most coveted biofuel, not only because of its tendency to reduce greenhouse gas emissions and other undesirable impacts associated with climate change, but also because of the simplicity of its methodology. This study evaluated bioethanol production from cocoa waste hydrolysates at the laboratory scale and, then evaluating the environmental impact associated with this production. Acid treatment was carried out on the hydrolysate in order to make it more accessible to ethanol-producing microorganisms. The cocoa hydrolysate was converted on a laboratory scale into bioethanol. The Ca, Mg, K and Na content of the substrate were respectively 78.4 ± 0.04; 109.59 ± 0.03; 1541.53 ± 0.08 and 195.05 ± 0.12 mg/L. The iron and total phosphorus contents were found to be at 14.06 ± 0.07 and 97.54 ± 0.01 mg/L respectively. The hydrolysate's biochemical oxygen demand (BOD 5) was 1080 ± 0.01 mg/L. A two per cent alcohol yield was obtained from 50 mL of substrate. Environmental impacts were assessed and quantified using SimaPro software version 9.1.1.1, Ecoinvent v.3.6 database, ReCiPe Midpoint v.1.04 method and openLCA sustainable development software. A total of 15 impact factors were assessed and quantified. The categories with more significant impacts in the agricultural phase were land use (1.70 E+04 m
