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

backgroundThe validation of the multi-ethnic GLI-2012 spirometric norms has been debated in several countries. However, its applicability in Algeria has not been verified.

aimTo ascertain how well the GLI-2012 norms fit contemporary adult Algerian spirometric data.

methodsThis was a cross-sectional study of a convenience sample of 300 healthy non-smoker adults (50% men, age range: 18-85 years) recruited from the Algiers region general population. All participants underwent a clinical examination and a plethysmography measurement. Z-scores for some spirometric data [FEV1, FVC, FEV1/FVC and forced expiratory flow at 25-75% of FVC (FEF25-75%)] were calculated. If the average Z-score deviated by "< ± 0.5" from the overall mean, the GLI-2012 norms would be considered as reflective of contemporary Algerian spirometry.

resultsThe means±SDs of age, height, weight, FVC, FEV1, FEV1/FVC and FEF25-75% of the participants were, respectively, 48±17 years, 1.65±0.10 m, 73±14 kg, 4.04±1.04 L, 3.18±0.82 L, 0.79±0.05 and 4.09±1.09 L/s. Almost the quarter of participants were obese. The total sample means±SDs Z-scores were 0.22±0.87 for FVC, 0.04±0.88 for FEV1, -0.34±0.67 for FEV1/FVC and 0.93±0.79 for FEF25-75%. For men and women, only the means±SDs of the FEF25-75% Z-scores exceeded the threshold of "± 0.5", respectively, 1.13±0.77 and 0.73±0.76.

conclusionResults of the present study, performed in an Algerian population of healthy non-smoking adults, supported the applicability of the GLI-2012 norms to interpret FEV1, FVC and FEV1/FVC but not the FEF25-75%.
