Effect of rifampin on steady-state pharmacokinetics of atazanavir with ritonavir in healthy volunteers.
Trial report in Antimicrobial agents and chemotherapy, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 34 papers, 1 of them a synthesis that pooled 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.
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
Mycobacterium tuberculosis is a concern in patients with human immunodeficiency virus (HIV) infection. Rifampin (RIF), an agent used against M. tuberculosis, is contraindicated with most HIV protease inhibitors. Atazanavir (ATV) has clinical efficacy comparable to a standard of care regimen in naive patients and, when dosed with low-dose ritonavir (RTV), also in treatment-experienced patients. We evaluated here the safety and pharmacokinetics of ATV, resulting from three regimens of ATV, RTV, and RIF in 71 healthy subjects. The pharmacokinetics for ATV and RTV were assessed after 6 and 10 days of dosing with ATV 400 mg (n = 53) and with ATV-RTV at 300 and 100 mg (ATV/RTV 300/100; n = 52), respectively. Steady-state pharmacokinetics for ATV, RTV, RIF, and desacetyl-rifampin (des-RIF) were measured after 10 days of dosing of ATV/RTV/RIF 300/100/600 (n = 17), ATV/RTV/RIF 300/200/600 (n = 17), or ATV/RTV/RIF 400/200/600 (n = 14). An RIF 600-alone arm was enrolled as a control group (n = 18). With ATV/RTV/RIF 400/200/600, ATV area under the concentration-time curve values were comparable, but the C(min) values were lower relative to ATV 400 alone. ATV exposures were substantially reduced for the other RIF-containing regimens relative to ATV 400 alone and for all regimens relative to ATV/RTV 300/100 alone. RIF and des-RIF exposures were 1.6- to 2.5-fold higher than with RIF 600 alone. The incidence of grade 3/4 alanine aminotransferase/aspartate aminotransferase values was limited to 1 subject each in both the ATV/RTV/RIF 300/200/600 and the ATV/RTV/RIF 400/200/600 treatments. Coadministration of ATV with RIF was safe and generally well tolerated. Since ATV exposures were reduced in all regimens, ATV and RIF should not be coadministered at the dosing regimens studied.
