The impact of health education intervention on knowledge, attitude, and practice of office workers about office ergonomics: a randomized controlled trial.
Trial report in BMC public health, 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
backgroundErgonomics is fundamental to improving safety and efficiency in offices. Therefore, the purpose of this study was to assess the effect of a health education intervention on office workers' knowledge, attitude, and practice (KAP) regarding ergonomics and to determine their predictors.
methodsFor this intervention study, 230 office workers were split into two equal groups. A validated KAP office ergonomics questionnaire and a health education intervention were given to the intervention group, while the control group only received the questionnaire. Three months later, both groups received a post-test questionnaire.
resultsThe post-test KAP scores of the intervention group were significantly higher than those of the control group (37.2 versus 30.9, 23.4 versus 28.3, and 17.0 versus 10.3, respectively, P < 0.05). Workers' office ergonomics knowledge, attitude, and practice scores significantly improved following the health education intervention (P < 0.05). Adequate knowledge and a positive attitude were significantly predicted by being younger (adjusted OR: 7.8 and 10.7), having a high level of education (adjusted OR: 8.9 and 2.5), using a computer (adjusted OR: 7.0 and 5.0), working long hours on a computer (adjusted OR: 3.1 and 3.0), and having a short job duration (adjusted OR: 5.2 and 12.3) within the intervention group. There was a significant positive correlation between the knowledge and practice scores (r = 0.469, P < 0.05).
conclusionsThe outcomes of the study demonstrated that office workers who received health education had significantly enhanced their KAP after a three-month follow-up. This highlights the importance of office workers' ergonomics education to ensure workplace safety and improve their well-being and productivity.
trial registrationThe study was retrospectively registered at the Pan African Clinical Trial Registry (PACTR) (ID: PACTR202604893125732) on 29 April 2026.
