1 · What the graph read from 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.

2 · The registry

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

Background: In trials, 3-month weekly rifapentine and isoniazid (3HP) showed higher adherence and completion than the 6-month daily isoniazid (6H) regimen for TB preventive treatment (TPT). However, programmatic outcome data remain limited. Methods: We evaluated the TPT cascade among people with HIV (PWH) aged ≥15 years newly enrolled in HIV care in western Kenya. Initiation and completion of 6H (Jan-Sept 2022) were compared to 3HP (Oct 2022-Sept 2023) using χ Results: Of 1930 PWH (median age 33 years [IQR=27-41]), 65.8% were female, and 19.5% had advanced HIV disease (AHD) at enrollment. Overall, 1922 (99.6%) were screened for active TB, of whom 1790 (97.5%) were TPT-eligible; 1577 (88.1%) of these initiated TPT. TPT initiation was higher with 3HP than 6H (89.8% vs 84.2%; Conclusions: TPT initiation was significantly higher after 3HP implementation. However, 3HP completion was similar to 6H. Targeted interventions are needed to support 3HP completion, particularly in PWH with AHD.
