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
Study was conducted during the main cropping season of 2016 in Fogera and Libo Kemkem District, South Gondar, Ethiopia to evaluate agro-morphological and physiochemical studies of upland rice (Oryza sativa L.) varieties for variability and their association with yield and their quality. A total of ten up land rice varieties namely NERICA13, NERICA12, NERICA4, SUPERICA1, HIDASE, ADET, ANDASA, TANA, KOKIT and GETACHEW laid down in a randomized complete block design with three replications were used. The study revealed significance (P < 0.05) difference in ago-morphological parameters like plant height, number of spike lets, biomass yield, straw yield, grain yield and harvest index in Fogera district, and productive tillers, number of spike lets, grain yield and harvest index in Libo Kemkem District. At Fogera district the highest yield were recorded in NERICA13 (4738 kg/ha), GETACHEW (4614 kg/ha), NERICA4 (4092 kg/ha), NERICA12 (4020 kg/ha) and Adet (3557.4 kg/ha) varieties, and NERICA12 (4583 kg/ha), NERICA13 (4013 kg/ha) NERICA4 (4002 kg/ha) and Adet (3380 kg/ha) varieties at Libo Kemkem districts. Five varieties (NERICA (4, 12 and 13), GETACHEW and ADET) at both locations had been tested for physicochemical analysis. The result showed that such rice varieties grain have a cooking grain length of 7.39 mm (ADET), 7.68 mm (NERICA4), 7.65 mm (NERICA12), 7.88 mm (NERICA13) and 6.76 mm (GETACHEW); cooking grain width of 2.61 mm (ADET), 2.64 mm (NERICA4), 2.70 mm (NERICA12), 2.79 mm (NERICA13) and 2.91 mm (GETACHEW); Grain thickness of 1.91 mm (ADET), 2.73 mm (NERICA4), 2.69 mm (NERICA12), 2.72 mm (NERICA13) and 2.23 mm (GETACHEW. and grain length/width (L/w) ratio 2.67 mm (ADET), 1.85 (NERICA4) 1.80 (NERICA12), 1.92 (NERICA13) and 2.09 (GETACHEW) were revealed and determination of grain shapes. Broken density was obtained 85.74mg/cm3 (ADET), 83.47mg/mm3 (NERICA4), 84.38mg/mm3 (NERICA12), 87.5mg/mm3 (NERICA13) and 73mg/mm3 (GETACHEW). Also investigations showed that upland rice grains contained 11.63-14.27% moisture; 1-1.24%, ash; 2.90-3.62% fiber and 8.07-10.35% protein. Gelatinization Temperatures ranged from 58.33 to 72.67% and grain contents of carbohydrates 73.57-75.65% were shown and significantly affected among their five upland rice grains varieties. Among the treatments of upland rice varieties were gained 35.79% of grain yield advantageous over all treatments at both locations. The results revealed in relatively morphologically and physicochemical properties of the three types of upland rice varieties NERICA (4, 12 and 13) were recommended to maximizing grain yielding for rice producing farmers.
