Finding missing TB cases in Northern Nigeria.
Article in Public health action, 2025. 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
settingDespite recent progress in TB notification rates, 6.2% of the 3.1 million 'missing' people with TB globally are from Nigeria. Identifying these 'missing' cases will improve TB control efforts in Nigeria.
objectiveThis paper aims to describe the outcome of an intensified TB case-finding strategy in northern Nigeria.
designAn intensified TB case-finding strategy was implemented in four states in northern Nigeria from October 2021 to September 2022. Trained ad-hoc staff screened hospital attendees and linked identified persons with presumptive TB to diagnosis using a hub and spoke approach. People with confirmed TB were linked to treatment. Contributions of the strategy to the national TB notification rates for each state were assessed.
resultsA total of 1.17 million individuals were screened for TB across the four project States. 64,079 people with presumptive TB were identified, of which 10.1% were diagnosed with TB and 97% of those diagnosed were placed on treatment. Averagely, 33.3% of the TB cases notified from each state were contributions from the hospital-based Intensified TB case-finding intervention.
conclusionFacility-based intensified TB case-finding results in significant improvement in TB notification rates and a good strategy to improve the identification of missing TB cases in Nigeria.
