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
study questionDo therapeutic levels of cyclosporine-A and tacrolimus affect ovulation in a rat gonadotrophin-induced ovulation model? SUMMARY ANSWER: Cyclosporine-A, but not tacrolimus, decreases ovulation rate when administered for 5 days before induced ovulation. WHAT IS KNOWN ALREADY: The mainstays of immunosuppression in solid organ transplantation, to prevent rejection, are the calcineurin inhibitors cyclosporine-A or tacrolimus. These drugs could potentially affect fertility in transplanted patients. Since ovulation is an inflammation-like process with pivotal roles for several immune cells and modulators, it is possible that the calcineurin inhibitors, with broad effects on the immune system, could interfere with this sensitive, biological process. STUDY DESIGN SIZE DURATION: Experimental design at university-based animal facilities. A total of 45 immature Sprague-Dawley rats were used. The study was carried out over 3 months. PARTICIPANTS/MATERIALS SETTING
methodsImmature Sprague-Dawley rats (n = 45) were randomly assigned to receive equivalent doses of tacrolimus (0.5 mg/kg/day; TAC), cyclosporine-A (10 mg/kg/day; CyA) or vehicle (Control). Ovarian hyperstimulation was induced with 10 IU of equine chorionic gonadotrophin, and ovulation was triggered with 10 IU of hCG. Oocytes were retrieved from the oviducts and ovulation rates were calculated. Various subpopulations of white blood cells were counted in peripheral blood and ovarian tissue samples. MAIN RESULTS AND THE ROLE OF CHANCE: Animals in the CyA group showed a lower ovulation rate when compared to the TAC and Control groups (CyA: mean 9 oocytes (range 0-22); TAC: 21 oocytes (8-41); Control: 22 oocytes (6-39); LIMITATIONS REASONS FOR CAUTION: Although the ovulation process is highly conserved within species, the differences between rodents and humans may limit the external translatability of the study. WIDER IMPLICATIONS OF THE
findingsThese findings suggest that tacrolimus should be the preferred calcineurin inhibitor of choice in transplanted patients who are aiming for pregnancy.
