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

backgroundIn rheumatism patients, the immune system erroneously attacks the body's own tissues. This impairs the body's defense against external pathogens and is a contributing factor to the occurrence of tuberculosis infection. The primary objective of this investigation was to examine the risk factors for the progression from latent tuberculosis infection (LTBI) to active tuberculosis (ATB) in patients with rheumatic diseases (RD).

methodsRD cover a wide range of disorders affecting the skeletal system, joints, and adjacent soft tissues. When the human body is infected by Mycobacterium tuberculosis, the condition is classified as either LTBI or ATB, depending on the presence or absence of typical clinical symptoms. A retrospective study was conducted at the Xijing Hospital of the Fourth Military Medical University. Specifically, the Laboratory Information System was used to investigate patients diagnosed with RD from January 2012 to October 2022.

resultsThe study included a total of 32,235 individuals diagnosed with rheumatism, of whom only 18.60% were screened for LTBI. The overall incidence of LTBI was 25.33%. Among the 629 RD inpatients with LTBI, systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) accounted for half, and 56.44% received glucocorticoid (GC) therapy. Risk-factor assessment for ATB was conducted in 247 cases. A GC dose of 20 mg/day or more was an independent risk factor for LTBI activation (odds ratio = 3.59, 95% CI: 1.26-10.29, p = 0.017).

conclusionIn China, RD patients have a relatively high risk of LTBI. In clinical practice, LTBI screening should be routinely performed for RD patients before initiating GC therapy at a dose of ≥ 20 mg/day. For patients with SLE and RA undergoing continuous GC treatment, close monitoring is essential. In addition, clinicians should enhance the diagnostic pathways and treatment management for these patients to prevent the occurrence of ATB.
