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
backgroundPulmonary tuberculosis can spread by airborne transmission when an infected person coughs, sneezes and speaks via expectorates. Therefore, household contacts who are close to a tuberculosis patient are at the highest risk of contracting the disease. This analytical cross-sectional study aimed to determine the factors affecting prevention behaviors among household contacts in Phitsanulok Province, northern Thailand.
methodsThe study sample included 193 household contacts with pulmonary tuberculosis in Phitsanulok Province. They were randomly selected using a multistage sampling technique. Data were collected by a self-administered questionnaire consisting of 8 parts: (1) sociodemographic characteristics, (2) tuberculosis knowledge, (3) perceived susceptibility of tuberculosis infection, (4) perceived severity of tuberculosis, (5) perceived self-efficacy of tuberculosis prevention, (6) perceived outcome of tuberculosis prevention, (7) social support of tuberculosis prevention, and (8) tuberculosis prevention behaviors. Frequencies, percentages, means, standard deviations, and multiple regression analysis were explored for data analysis.
resultsMost participants (91.2%) had tuberculosis prevention behaviors at a high level (scores of 4.35). Factors that significantly affected tuberculosis prevention behaviors included perceived self-efficacy in tuberculosis prevention (β = 0.474), social support (β = 0.220), current smoker (β = -0.171), driving to the hospital (β = 0.150), unknown history of tuberculosis vaccination (BCG) (β = -0.122), and those who were older siblings, aunts, uncles, younger siblings, or nephews of participants (β = -0.116). These 6 factors explained 38.5% of tuberculosis prevention behaviors.
conclusionHousehold contacts to pulmonary tuberculosis should be educated about the perceived self-efficacy of tuberculosis prevention, and receive more social support to prevent the disease. The focus should be on current smokers, those who drive to the hospital, those who do not know the history of tuberculosis vaccination, and relatives of patients (older sibling, aunt, uncle, younger sibling, nephew) to reduce the risk of pulmonary tuberculosis in the future.
