Prevalence of malnutrition among old people in Africa: systematic review and meta-analysis.
Synthesis in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06823739 (Personalized Diet with or Without Physical Exercise Improves Nutritional Status, Muscle Strength, Physical Performance and Quality of Life in Malnourished Older Adult Patients), which is not on this map. Cited by 11 papers, 3 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.

Abstract
objectiveTo summarise available evidence and estimate the pooled prevalence of malnutrition among old people in Africa.
designSystematic review and meta-analysis.
settingAny healthcare or community research reporting the prevalence or incidence of malnutrition in Africa from January 2000 to October 2021.
participantsOld people, aged above 60 years. OUTCOME MEASURES: Malnutrition, either undernutrition or overnutrition.
resultsA total of 1442 studies were retrieved based on the search strategy, where only 36 studies (n=15 266 participants) reported from 11 African countries were included for meta-analysis. The reported prevalence of malnutrition ranges from 2.2% to 77.3% across the continent. Overall, the pooled prevalence rates of undernutrition and overnutrition were 18% (95% CI: 15% to 22%; I
conclusionThe prevalence of malnutrition in old African people is high and differs by setting, assessment tool and country of residence. Hence, due attention to geriatric nutrition is mandatory, and the need for a valid, reliable and simple screening tool should be thought of.
