1 · What the graph read from it

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.

2 · The registry

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

Purpose: Cannabis use has reportedly increased in type 2 diabetic users as a possible co-treatment for associated pain and inflammation. Both cannabis and metformin (an anti-diabetic drug) have a limited number of studies completed on their effect on male reproductive parameters in a diabetic model. This study determined if cannabis and metformin administration alter various reproductive parameters in diabetic male rats. Methods: Male Wistar rats (n = 35) were fed on a high fat diet and injected with streptozotocin (30 mg/kg rat) to induce a type-2 diabetic model. Treatment groups received cannabis based on Delta-9-Tetrahydrocannabinol (THC) concentrations of 1.25, 2.5 and 5 mg/kg per rat and metformin (50 mg/kg) every alternate day for 10 weeks. Organ weight; serum testosterone levels and sperm count, motility, lipid peroxidation, citrate synthase and lactate dehydrogenase activities were measured. Results: Cannabis treatment induced a significant concentration dependent decrease in sperm motility at 5 mg/kg rat THC ( Conclusions: Cannabis needs to be used cautiously as an alternative treatment in diabetic males based on the negative effects observed for the various reproductive parameters in this diabetic rat model.
