TB programme outcomes in South Fly District, Papua New Guinea, were maintained through COVID-19.
Article in Public health action, 2024. 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
settingAn established response to an outbreak of drug-resistant TB (DR-TB) on Daru Island, South Fly District (SFD), Western Province, Papua New Guinea (PNG).
objectiveTo describe and evaluate the trends in TB case notification disaggregated by demographic and clinical characteristics, programmatic interventions for TB and COVID-19 and treatment outcomes in 2017-2022.
designA cohort study of routinely collected programmatic data of all patients registered for TB treatment in SFD comparing pre-COVID (2017-2019) to COVID (2020-2022) periods.
resultsOf the 3,751 TB cases registered, 19.6% had DR-TB, and the case notification rate was 1,792/100,000 for Daru and 623/100,000 for SFD. There was a 29.2% reduction in case notifications from 2019 to 2021, with recovery in 2022. During COVID, the healthcare workforce was adversely impacted, and active TB case-finding was stopped. During COVID, compared to pre-COVID, bacteriological confirmation increased (62.3% to 71.9%), whereas rates of child TB notifications (11.6% to 9.1%), pulmonary TB (60.8% to 57.4%) and DR-TB (20.7% to 18.6%) decreased. High rates of treatment success were maintained for both drug-susceptible (86.5%) and DR-TB (83.6%).
conclusionHealth systems strengthening and community engagement before COVID likely contributed to resilience and mitigated potential impacts on TB in this remote and resource-limited setting. Case notifications remain very high, and additional interventions are needed to interrupt transmission.
