Increased detection of latent tuberculosis by tuberculin skin test and booster phenomenon in early rheumatoid arthritis patients.
Observational study in Rheumatology international, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
The incidence of tuberculosis (TB) in rheumatoid arthritis (RA) patients is up to four times higher when compared to the general population, but their risk increases with the use of TNF-a drugs. Appropriate screening of latent tuberculosis infection (LTBI) and proper management of such cases substantially reduce the incidence of active TB. Tuberculin skin test (TST) is a widely used method for the detection of LTBI. The time of diagnosis of RA as well as the age of the patient might modify the TST performance. We did an observational, comparative study of RA patients with early and established disease, with the objective to know the prevalence of LTBI using the TST and booster test; an induration ≥5 mm was considered reactive. We evaluated 143 patients (83 [58 %] early RA patients). We found 31.3 and 21.7 % TST positivity in early and established RA patients, respectively. With the use of booster test, the positivity increased to 46.5 and 28.8 %, respectively (p = 0.048, OR 1.33, 95 % CI 1.01-1.75). In conclusion, we found that TST and booster test increased LTBI detection in early RA patients, which may suggest that time of RA diagnosis might affect cellular immunity and therefore the TST response.
