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
objectivesLeptin is a novel and interesting hormone for anyone trying to lose weight, but its effects on male gonad structure in longitudinal study is unknown. The present study was designed to explore morphometrical changes of mouse testicular tissue after long-term administration of leptin. MATERIALS AND
methodsThirty healthy mature male mice were randomly assigned to either control (n=15) or treatment (n=15) groups. Leptin was intraperitoneally injected to the treatment group (0.1 µg/100 µl of physiological saline) once a day for 30 consecutive days, and control animals received normal saline with the same volume and route. Five mice from each experimental group were sacrificed at 15, 30 and 60 days after the beginning of treatments. Left testes were removed, weighted and then fixed in 10% buffered formalin, and stained with hematoxylin and eosine for morphometrical assays.
resultsExcept for sertoli cell nucleus diameter, which was affected from 30(th) day, evaluation of other morphometrical parameters such as Johnsen's score, meiotic index, spermatogenesis, epithelial height, seminiferous tubules diameter and spermatogonial nucleus diameter revealed significant decrease from 15(th) day after leptin administration compare to those of the control group (P<0.05). Thus, meiotic index and spermatogonial cell nucleus diameter were two parameters that were further disturbed on 30(th) day compare to the day 15 (3.09±0.03 vs. 3.23±0.03, P=0.006 and 5.50±0.09 vs. 6.08±0.14, P=0.007, respectively).
conclusionOur results showed that long-term administration of leptin could disturb testicular tissue structure and delay spermatogenesis process.
