Effect of HIV infection and menopause status on raltegravir pharmacokinetics in the blood and genital tract.
Trial report in Antiviral therapy, 2015. 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
backgroundThis study describes first dose and steady state pharmacokinetics of raltegravir (RAL) in cervicovaginal fluid (CVF) and blood plasma (BP).
methodsThree cohorts of women were enrolled sequentially in a single-site, open-label pharmacokinetic study of oral raltegravir 400 mg twice daily: HIV-negative premenopausal, HIV-infected premenopausal and HIV-infected post-menopausal women. BP and CVF were collected over 12 h after a single observed dose and at steady state. RAL concentrations were measured by HPLC-MS methods. Data are expressed as median (IQR). The ANOVA rank-sum test was used to evaluate between-group differences in steady state raltegravir exposure (area under the concentration-time curve over the 12-h dosing interval [AUC0-12 h]).
resultsFirst dose pharmacokinetics were obtained in HIV-negative premenopausal women and HIV-infected post-menopausal women only. The median (IQR) BP AUC0-12 h was 3,099 (985-5,959) and 4,239 (2,781-13,695) ng•h/ml and the median (IQR) CVF AUC0-12 h was 1,720 (305-5,288) and 13,797 (11,066-19,563) ng•h/ml for HIV-negative premenopausal and HIV-infected post-menopausal women, respectively. All cohorts contributed to steady-state pharmacokinetic profiles. Median (IQR) BP AUC0-12 h did not differ between the groups: 8,436 (3,080-10,111), 5,761 (1,801-10,095) and 6,180 (5,295-8,282) ng•h/ml in HIV-negative premenopausal, HIV-infected premenopausal and HIV-infected post-menopausal women, respectively. There was a trend for lower CVF AUC0-12 h among HIV-negative women 3,164 (1,156-9,540) compared to 11,465 (9,725-17,138) and 9,568 (4,271-24,306) ng•h/ml HIV-infected premenopausal and HIV-infected post-menopausal women, respectively, but this was not statistically significant (P=0.08). HIV-negative premenopausal women had a median (IQR) CVF:BP AUC0-12 h ratio of 0.46 (0.2-1.1), whereas HIV-infected premenopausal and post-menopausal women had median (IQR) CVF:BP AUC0-12 h ratio of 3.9 (1.2-6.7) and 1.4 (0.7-4.3), respectively.
conclusionsThis is the first study to investigate RAL exposure in BP and CVF in premenopausal HIV-negative and pre- and post-menopausal HIV-infected women. These data indicate HIV and menopausal status may influence antiretroviral distribution into the female genital tract.
