Walking as a feasible means of effecting positive changes in BMI, waist, and blood pressure in black South African women.
Trial report in African health sciences, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundIn the context of a growing obesity pandemic in sub-Saharan African countries little is known on how to address the problem /disease in the region.
methodsA randomised controlled trial of walking to decrease obesity was conducted using 115 women employed at the University of Venda, Limpopo province. 49 of these participants were randomly selected into an intervention group, which walked for 30 minutes, 3 days per week for a period of 12 weeks on treadmills located in the university gym. The control group were instructed to continue with usual activities. Baseline and follow-up body mass index (BMI), waist circumference, blood pressure (BP), body size discrepancy (measured by a feel-minus-ideal (FID) index), and physical activity were collected on all participants.
resultsThe absolute changes in BMI, waist, systolic and diastolic BP in the intervention group was -0.80, -1.50, -4.02 and -2.37, respectively. In contrast, the absolute changes for these were +1.05, +1.73, +4.64 and +4.94, respectively in the control group. The results of the FID analysis showed that most had a desire for thinness.
conclusionOur data demonstrates that positive changes in BMI, waist, and BP were observed in the intervention group, indicating the potential scalability of the intervention.
