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

backgroundAnemia is a common health issue among adolescents. Anemic conditions could affect physical performance; however, the actual profiles of anemia in adolescent students in sports clubs have not been well documented.

methodsWe conducted a retrospective chart review of individuals aged 13-22 years who belonged to sports clubs in schools and visited an outpatient clinic between August 1, 2016, and August 31, 2020. The medical and laboratory records, including serum levels of ferritin, folate, vitamin B12, and creatinine kinase at their first visit were assessed.

resultsA total of 485 individuals (231 male (48%) and 254 female (52%) patients) were eligible for the study. The most common club activity was track and field ( DISCUSSION: Anemia is prevalent in both male and female adolescent students in sports clubs. Iron deficiency and excessive training indicated by elevated creatinine kinase levels may contribute to the risk of anemia. Physicians should assess the amount of exercise, and not merely iron storage, in clinical practice.
