Effect of physiological characteristics, smoking, and alcohol use on isoniazid hair drug levels among pulmonary TB patients: a cross-sectional study at one month of intensive TB treatment.

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
Background: Tuberculosis(TB) is still among the leading causes of death from a single infectious pathogen worldwide. TB treatment is long, requires multiple drug combinations, and therefore adherence monitoring. TB hair drug levels have been suggested as a technique of treatment adherence monitoring; however, the drug levels might be affected by physiological factors, alcohol use, and cigarette smoking. This can affect the pharmacokinetics and pharmacodynamics of TB drugs. Objective: To assess the effect of physiological factors, smoking, and alcohol on isoniazid hair drug levels during TB treatment. Methods: Patients were assessed for diabetes Mellitus, smoking, alcohol consumption, age, weight, and gender. Hair drug levels were measured by Liquid Chromatography Mass Spectrometry(LC-MS). Results: We screened a total of 102 TB patients and enrolled 56 participants out of which 50 completed the study. We excluded 15 participants who were not sampled exactly at 1-month appointment dates and of the remaining 35; the mean hair drug level was 0.0706ng/mg, 95% CI: 0.0303-0.1109. Tests of interaction across the different subgroups yielded no statistically significant interaction coefficients(IC) except for age and gender (IC=-0.36.95%, CI: -0.55-0.17, P=0.001). Conclusion: Physiological factors, alcohol, and smoking do not affect isoniazid hair drug levels.
