Comparison of body composition changes between atazanavir/ritonavir and lopinavir/ritonavir each in combination with tenofovir/emtricitabine in antiretroviral-naïve patients with HIV-1 infection.
Trial report in Clinical drug investigation, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
BACKGROUND AND
objectiveAntiretroviral drug regimen choice may influence changes in body composition. The objective of this study was to compare changes in body composition between ritonavir-boosted atazanavir (ATV/r) and ritonavir-boosted lopinavir (LPV/r) over 96 weeks using data from a substudy of CASTLE, which compared once-daily ATV/r with twice-daily LPV/r, both in combination with tenofovir disoproxil fumarate/emtricitabine in treatment-naïve patients with HIV-1 infection.
methodsWe examined 224 patients (125 on ATV/r; 99 on LPV/r) at baseline, 48 and 96 weeks using dual-energy X-ray absorptiometry and computerised tomography.
resultsIn the lowest baseline body mass index (BMI) group, there were significantly greater gains at week 96 for ATV/r than for LPV/r in subcutaneous adipose tissue and in visceral adipose tissue (VAT). By week 96, patients with lowest baseline CD4 cell counts on ATV/r had 28 % increases in VAT versus 14 % reductions for patients receiving LPV/r. Those with the lowest baseline BMI on ATV/r had 19 % increases in VAT versus reductions of 5 % for patients on LPV/r. In the highest baseline BMI group, the mean increase in triglycerides was 6 and 70 % in the ATV/r and LPV/r arms, respectively. Compared with baseline, an increase in proportion of patients with high waist circumference (WC)/high triglycerides at 96 weeks was noted in both treatment arms, but this increase was numerically greater with LVP/r (18 %) than with ATV/r (11 %).
conclusionTruncal fat gains on ATV/r primarily led to increases in WC, which may reflect return to health, while on LPV/r increases in WC and triglycerides occurred. Changes in body composition with antiretroviral therapy are influenced by treatment choice and baseline characteristics.
