Concentrations of cortisol, testosterone and glycosylated haemoglobin (HbA1c) among construction workers with 12-h workdays and extended workweeks.

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
objectivesWorking on large scale construction sites have been shown to have severe health consequences in terms of increased risk of hospitalization and disability retirement compared to construction work in general. The aim of the present study was to investigate whether large scale construction work involving 12-h workdays and extended workweeks leads to insufficient recovery measured as increased catabolic and decreased anabolic metabolism.
methodsThe study group comprised 40 male construction workers of which 21 had 12-h workdays and extended workweeks (56 h/workweek). The comparison group consisted of 19 male construction workers, who worked regular hours (37 h/week, weekends off). Measurements of concentrations of cortisol in saliva and free testosterone and glycosylated haemoglobin (HbA(1c)) in blood were made in a repeated measures design during 2 workweeks for both groups supplemented with 1 week off for construction workers with extended workweeks.
resultsThe diurnal profile of concentrations of salivary cortisol for construction workers with extended workweeks differed from the diurnal profile of salivary cortisol for those with regular work schedules (P < 0.001). The construction workers with extended workweeks tended to have 15% [95% CI -3%; 37%] higher concentrations of free testosterone in serum compared to construction workers with regular work schedules (P = 0.09). There were no differences between the two groups with respect to concentrations of HbA(1c). There was no increasing trend in concentrations of cortisol or decreasing trend in concentrations of testosterone during the extended workweek. The diurnal profile for concentrations of cortisol differed between workdays and days off for construction workers with extended workweeks (P = 0.003).
conclusionIn conclusion, we observed no indications of insufficient recovery in terms of increased catabolic or decreased anabolic metabolism in construction workers with 12-h workdays and extended workweeks compared to construction workers with regular work schedules.
