1 · What the graph read from 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.

2 · The registry

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 Pure red cell aplasia (PRCA) is an uncommon syndrome characterized by ineffective erythropoiesis and severe anemia. Among immunodeficient patients, including those with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), persistent parvovirus-B19 can cause PRCA. We report a rare case of an Australian man with parvovirus-B19 mediated PRCA secondary to a new diagnosis of HIV-1/AIDS. The case highlights the importance of early treatment initiation with anti-retroviral drugs and pooled immunoglobulins to enable marrow recovery and long-term disease remission. CASE REPORT A 64-year-old man residing in rural Indonesia presented with severe anemia. Apart from 8 kg of unintentional weight loss, he denied any occult bleeding, diatheses, or constitutional symptoms. His bloodwork revealed a normocytic, normochromic anemia (Hb 81 g/L) with profound reticulocytopenia (9.5×10⁹/L). Parvovirus-B19 serology and polymerase chain reaction testing confirmed active viremia. Lymphopenia and an undetectable CD4 T-lymphocyte count (<1%) were also noted; HIV-1 was subsequently diagnosed. Bone marrow sampling later confirmed features consistent with parvovirus-B19-driven PRCA secondary to HIV-1/AIDS. The patient received 1 g/kg intravenous immunoglobulin for two days and initiated anti-retroviral HIV therapy. Rapid reticulocytosis with slow incrementation of his hemoglobin were observed over one month. At three years following his diagnosis, he remains in remission. CONCLUSIONS Severe, isolated anemia in immunodeficient patients, particularly those with HIV-1/AIDS, should prompt consideration of parvovirus-B19-mediated PRCA. Depletion of CD4-T-lymphocyte populations enables the establishment of parvovirus-B19 reservoirs within erythroid progenitors, thereby hampering physiological erythropoiesis. Long-term remission can be achieved with the rapid institution of intravenous immunoglobulin and anti-retroviral HIV therapies.
