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
backgroundIschemia and reperfusion (I/R) lead to cellular damage. A disturbance of testicular perfusion occurs during the therapy of cryptorchidism and in cases of testicular torsion. This results in the activation of mediator cells with an increasing synthesis of mediators of infection like TNF-alpha and the expression of cell adhesion molecules like ICAM (intercellular adhesion molecule) and VCAM (vascular cell adhesion molecule) at the cellular surface.
methodsThe expression of the cytokines IL-10 and TNF-alpha and the adhesion molecules ICAM and VCAM after defined testicular I/R injury in nine male transsexuals was evaluated with rt-PCR. Furthermore we examined lactate and the diameter of the testicular tubulus under ischemic conditions.
resultsDuring ischemia ICAM, IL-10, and VCAM do not show significant changes on the side of testicular ischemia and the contralateral side; the same was seen for the tubulus diameter. TNF-alpha and the testicular lactate values showed a significant change of the expression pattern. DISCUSSION: The statistical changes of TNF-alpha and testicular lactate are the expression of leukocyte migration, infectious reaction, and immune response. To what extent the TNF-alpha expression represents a severe immunological reaction remains undefined. This human study shows primary results for the immunological understanding of and cellular response to testicular ischemia.
