LA sprouts randomized controlled nutrition and gardening program reduces obesity and metabolic risk in Latino youth.
Trial report in Obesity (Silver Spring, Md.), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 10 papers, 2 of them syntheses that pooled 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.
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
objectiveTo assess the effects of a 12-week gardening, nutrition, and cooking intervention ("LA Sprouts") on dietary intake, obesity parameters, and metabolic disease risk among low-income, primarily Hispanic/Latino youth in Los Angeles.
methodsThe randomized controlled trial involved four elementary schools [two schools randomized to intervention (172 third-through fifth-grade students); two schools randomized to control (147 third-through fifth-grade students)]. Classes were taught in 90-minute sessions once a week to each grade level for 12 weeks. Data collected at pre- and postintervention included dietary intake via food frequency questionnaire (FFQ), anthropometric measures [BMI, waist circumference (WC)], body fat, and fasting blood samples.
resultsLA Sprouts participants had significantly greater reductions in BMI z-scores (0.1-vs. 0.04-point decrease, respectively; P = 0.01) and WC (-1.2 cm vs. no change; P < 0.001). Fewer LA Sprouts participants had the metabolic syndrome (MetSyn) after the intervention than before, while the number of controls with MetSyn increased. LA Sprouts participants had improvements in dietary fiber intake (+3.5% vs. -15.5%; P = 0.04) and less decreases in vegetable intake (-3.6% vs. -26.4%; P = 0.04). Change in fruit intake before and after the intervention did not significantly differ between LA Sprouts and control subjects.
conclusionsLA Sprouts was effective in reducing obesity and metabolic risk.
