Prevalence of tobacco use in a cross-sectional survey of people initiating HIV care in a Chennai clinic.
Article in Scientific reports, 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
Objectives: We aimed to understand tobacco use and treatment patterns among adults starting care in a Chennai HIV clinic. Methods: Cross-sectional survey of adults initiating HIV care with biochemical verification of tobacco exposure. Results: Among 154 adult patients (10/2019-12/2021) initiating HIV care, 37.7% (n = 58) self-reported current tobacco use (13.6% [n = 21] smoking, 17.5% [n = 27] smokeless tobacco [SLT], 6.5% [n = 10] dual use) and 7.8% (n = 12) reported former use (5.8% [n = 9] smoking, 1.3% [n = 2] SLT, 0.6% [n = 1] dual), none reported using cessation medications, two reported counseling. Cotinine levels indicating current use varied by tobacco product (smoking: 66.7% had cotinine ≥ 50ng/ml; SLT: 70.4%; dual: 80.0%, no current tobacco: 44.8%, p = 0.02). Conclusion: Smoking and SLT use are common and underreported and evidence-based cessation treatment use was rare prior to HIV care initiation.
