DORA: 48-week weight and metabolic changes in Black women with HIV, in a phase IIIb switch study from dolutegravir- or efavirenz- to doravirine-based first-line antiretroviral therapy.

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
objectivesTreatment-related weight gain and metabolic complications with antiretroviral integrase-based regimens, especially among Black women, suggest the need for alternative options.
methodsWe conducted a 48-week, open-label, single-arm, single-centre, phase IIIb switch study to evaluate the tolerability, safety and efficacy of switching from stable efavirenz- or dolutegravir-based antiretroviral therapy to doravirine/lamivudine/tenofovir disoproxil fumarate in Black women.
resultsThe 101 participants enrolled (median age 35 years; interquartile range 31-40) were on efavirenz (n = 46; mean duration on therapy 1.7 years) or dolutegravir-based (n = 55; mean duration 1.5 years) antiretrovirals at screening. Retention at 48 weeks was 92/101 participants, and viral suppression was >90% throughout the study, with a single case of doravirine resistance (106 M, V108I and H221Y mutations). The mean weight percentage change at week 48 was 4.7% (95% confidence interval [CI] 3.0-6.5; p < 0.001), and the adjusted mean change was 2.7 kg (95% CI 1.50-3.98; p < 0.001); for efavirenz, the percentage change was 5.0% (95% CI 2.9-7.1; p < 0.001), and the adjusted weight gain was 3.5 kg (95% CI 1.93-5.13); for dolutegravir, the percentage change was 4.5% (95% CI 1.8-7.3; p < 0.001), and the adjusted weight gain was 2.1 kg (95% CI 0.26-3.90). Statistically significant decreases in lipid panel percent mean to week 48 included: total cholesterol -8.4% (95% CI -11.3 to -5.5; p < 0.001), triglycerides -10.4% (95% CI -16.4 to -4.4; p < 0.001) and high-density lipoprotein -14.8% (95% CI -18.5 to -11.2%; p < 0.001), with minor differences when disaggregating the mean percent change in lipids between previous efavirenz/dolutegravir regimens. Adverse events due to doravirine were few and mild.
conclusionsOur findings suggest that a switch to doravirine from efavirenz or dolutegravir is safe and effective in Black women, with significant improvement in lipid profiles, but does not arrest progressive weight gain.
