The immune response to the RT181-189 epitope in HIV-1-infected patients is associated with viral sequence polymorphism flanking the epitope.

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
Many drug-resistance mutations in HIV-1 reverse transcriptase fall within cytotoxic T lymphocytes (CTL) epitopes, but studies of the response to these epitopes in patients with virological failure are lacking. We therefore compared IFN-γ ELISPOT responses to the YV9 epitope (RT181-189) covering the lamivudine resistance mutation, M184V, in HLA-A2(+) antiretroviral treatment (ART)-naive patients (n = 19), to those found in HLA-A2(+) patients with virological failure (n = 15). Ten ART-naive patients had an ELISPOT response to the wild-type epitope that cross-reacted with the mutant epitope. Two patients with virological failure showed a specific response to the 184V mutant epitope. Responses against YV9 were strongly associated (p = 0.005) with the presence of a 177E mutation, and the same tendency was observed in an independent cohort of patients (n = 22). These results indicate that variants in flanking residues may influence CTL responses to conserved subdominant HIV-1 epitopes.
