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

We examined if creatine kinase (CK) activity differed between congested (CS) and non-congested schedules (NCS) in elite youth national team soccer players. The CK activity of 188 players (16.53 ± 1.78 years) was measured in national team training camps (2489 individual data points). Training load one day before the match (MD-1) was monitored with global positioning system (GPS) devices. CS occurred, when the athlete played at least 60 minutes in the previous 3 days leading into the match (MD). CK
