Calculating foreskin surface area based on glans measurements of 143 men using a simplified geometrical model of the foreskin.

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
Dimensions of male genitalia have received considerable scientific attention, but the foreskin has been largely omitted from these efforts. To calculate the foreskin surface area based on measurements of patients or voluntary study participants, we describe the foreskin in a simplified model as a tube of elastic tissue with a minimum length corresponding to that of the glans, and a minimum diameter corresponding to that of the corona in flaccid or erect state. To apply our model, we re-analysed previously collected data from a study of penile measurements. In this study from 2001, genitalia of 143 men aged 18 - 68 were measured in flaccid and erect state. Participants were recruited from secondary schools and hospitals, and penile measurements were performed once on a single day by a single medical doctor. We used this set of data to calculate the foreskin surface area and added 10% to the raw glans measurements to account for functional tissue elasticity. We found a median surface area of 79.8 cm
