ReviewTherapeutic advances in reproductive health
Mechanisms of action of currently available woman-controlled, vaginally administered, non-hormonal contraceptive products.
Review in Therapeutic advances in reproductive health. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Woman-controlled, vaginally administered contraceptives offer women discreet, self-administered, and reversible options. This brief report summarizes the mechanisms of action (MOAs) of currently available, woman-controlled, vaginally administered, non-hormonal products, excluding those that need to be fitted by a healthcare provider. MOAs of three general types of contraceptives will be reviewed, including pH modulators, spermicides, and barrier methods. The recently approved vaginal pH modulator (lactic acid, citric acid, and potassium bitartrate) has a non-hormonal MOA, acting as a buffering agent in the presence of alkaline semen and resulting in sperm immobilization. In contrast, spermicides, such as nonoxynol-9, act by lysing sperm membranes, resulting in sperm death. Barrier methods, such as the diaphragm and female condom, prevent sperm from entering the uterus. In addition to their varying MOAs, each woman-controlled, vaginally administered method has different instructions for use, efficacy, side effects, and availability/insurance coverage, thus providing a range of characteristics to fit different needs and preferences.
