Hepatitis B virus infection and 1q21 amplification in multiple myeloma.

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
Hepatitis B virus (HBV) is a hepatotropic and a lymphotropic virus. An association between HBV and hematologic malignancies has been determined previously; however, the association between HBV infection and multiple myeloma (MM) remains controversial. The present study aimed to assess the prevalence of HBV infection in patients with MM, and investigate their characteristics and prognostic significance. The clinical data of 165 patients with MM who had received at least four cycles of chemotherapy between April 2008 and February 2017 at Nanjing Drum Tower Hospital (Nanjing, China) were collected. HBV markers were determined using ELISA. The rates of acute or chronic HBV infection and resolved HBV infection in patients with MM were 12.12 and 26.06%, respectively. The gain of 1q21 was significantly more prevalent in the patients who were classified as HBV-positive compared with the patients who were classified as HBV-negative (54 vs. 38.2%; P=0.048), and the level of alanine transaminase in patients who were classified as HBV-positive was significantly increased compared with the non-infected group (63.29 vs. 24.66 U/l; P=0.043). Lactate dehydrogenase, serum creatinine and serum calcium levels were additionally determined to be significant risk factors of overall survival. The progression-free survival (PFS) of patients who were classified as HBV-positive was decreased compared with patients who were classified as HBV-negative (18.97 vs. 29.67 months; P=0.006), and being HBV-positive was determined to be an independent prognostic factor of PFS. HBV infection may contribute to MM progression through 1q21 amplification, and improved monitoring of HBV markers in patients with MM may be required.
