[Spirometric reference values in the Bantu population aged 20-70 years in Kinshasa].
Article in The Pan African medical journal, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionSpirometric reference values cannot be extrapolated in the populations, being subject to many environmental and human variables; hence the interest of local studies in this field.
methodsThis study aims to determine the reference values among healthy adults in Kinshasa. We conducted a cross-sectional study including 7443 subjects (3208 women, 43%). FEV1, FVC, PEF were correlated with anthropometric data. Five age groups were formed and comparisons were made on the basis of sex, age, BMI and of the practice of sporting activity.
resultsDifferences are evident between the sexes, in terms of FEV1 (3.00 vs 2.21 L), FVC (3.19 vs 2.38) and the PEF (6.8 vs 5.70 L/s); same as for the outer age categories. FEV1 ranged between 2.33 et 4.54 vs 1.93-3.3 L in the age group 20-29 years and 1,76-3,39 vs 1,60 vs 2,53 L in the age group 60-70 years; FVC ranged between 2,44-4,89 vs 1,96-3,56 L and 1,79-3,78 vs 1,66-2,74 L ; PEF ranged between 4,34-12.2 vs 3,62-8.58 L/s and 2.99-6.76 vs 2.99-7.34L/s in the age group 60-70 years.
conclusionThe differences related to gender, age, anthropometric data as well as to the practice of sporting activity are obvious. These results warrant further and more extended investigations and show the relevance of values based on percentiles in the determinantion of a spirometry standard in a given population.
