Investigation of an ongoing cluster of tuberculosis (TB) associated with prisons, England.
Article in Epidemiology and infection, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Prisons are high-risk environments for the spread of tuberculosis (TB). We investigated an ongoing prison-associated TB cluster to identify common exposures. We defined cases as residents in England with laboratory-confirmed TB belonging to the genetic cluster. We extracted records from the National TB Surveillance System, linked to prison operational data, and conducted descriptive analysis of demographic, clinical, and phylogenetic data. Years were masked for anonymity. Over six years, 12 individuals were identified, predominantly male (83%) and median age 34 years, in London, East Midlands, and East of England. Prison history was noted for 7/12 (58%) at 13 prisons. Everyone without prison history completed treatment, but 2/7 with prison history were lost to follow-up and 5/7 were still in treatment or outcome not evaluated. We identified frequent prison transfers and concurrent stays of four individuals at Prison B, and two at Prison G. Phylogenetic analysis indicated distinct sub-clusters with and without prison history, suggesting expansion of the cluster from community into prisons. Prisons continue to play a role in TB in England. Factors such as frequency of transfers could hinder treatment completion and control of transmission. Combining phylogenetic, epidemiological, and prison operational data facilitated investigation of transmission pathways.
