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

Foliar inputs from indigenous agroforestry tree/shrub provide organic matter and nutrients to sustain crop production in the West African Sahelian region. This study aims at monitoring the decomposition and nutrients release of leafy biomass of selected agroforestry tree and shrub species. In Mali and Burkina Faso, fresh leaves were collected from leguminous trees (Faidherbia albida (Delile) A. Chev., Pterocarpus lucens Lepr.) and non-leguminous trees (Vitellaria paradoxa C.F. Gaertn., Khaya senegalensis (Desr.) A. Juss.) and in Senegal, fresh leaves were obtained from leguminous trees (Faidherbia albida (Delile) A. Chev., Pterocarpus lucens Lepr. and Piliostigma reticulatum (DC.) Hochst.) and the non-leguminous tree Guiera senegalensis J.F. Gmel. The leaf samples collected during the dry and rainy seasons were deployed for decomposition and nutrient release experiments using the litter bag technique. Average decomposition rate for this study was 0.23 k week− 1 whereby the rate of decomposition was 155% higher in the rainy season than in the dry season. Average decomposition rate of leguminous tree and shrub leaves was 1.4-folds greater than that of non-leguminous counterparts. To optimize the synchronization of nutrient release from green manure with crop nutrient demands, manure should be co-applied considering seasonal and species effects.
