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
Sterile α motif and histidine/aspartic acid domain‑containing protein 1 (SAMHD1) can inhibit reverse transcription of human immunodeficiency virus‑1 (HIV‑1) by hydrolyzing intracellular deoxy‑ribonucleoside triphosphate. However, its role in HIV‑1 disease progression has not been extensively studied. To study the impacts of SAMHD1 on HIV‑1 disease progression, especially on DNA levels, we investigated SAMHD1 levels in the peripheral blood of HIV‑1 elite controllers (ECs), antiretroviral therapy (ART) naive viremic progressors (VPs) and patients with HIV‑1 receiving ART (HIV‑ARTs) compared with healthy controls. In addition, the present study analyzed the relationship between SAMHD1 and interferon‑α, immune activation and HIV‑1 DNA levels. The results of the present study demonstrated elevated SAMHD1 expression in the peripheral blood mononuclear cells of all patients withHIV‑1, but higher SAMHD1 expression in the CD4+ T cells of only ECs compared with healthy controls. Immune activation was increased in the VPs and decreased in the ECs compared with healthy controls. Substantially lower HIV‑1 DNA levels were identified in ECs compared with those in VPs and HIV‑ARTs. SAMHD1 expression was associated with low levels of immune activation. No significant correlation was observed between SAMHD1 and HIV‑1 DNA levels. Overall, the findings of the present study indicated that SAMHD1 was highly expressed in ECs, which may be associated with low immune activation levels, but was not directly related to HIV‑1 DNA levels.
