People in Brazil hold unhelpful beliefs about low back pain: An online survey using the back pain attitudes questionnaire.
Article in Brazilian journal of physical therapy, 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
backgroundBeliefs about low back pain (LBP) influence decisions about treatment, healthcare utilisation and engagement in valued activities. Beliefs in middle-income countries remain understudied.
objectivesTo explore beliefs about LBP in people with a history of LBP, no history of LBP, and with current LBP who live in a middle-income country (Brazil).
methodsThis is an online survey. Adults over 18 years of age living in Brazil, who currently experience LBP (current LBP), with a history of LBP, or with no history of LBP, were recruited. The Brazilian-Portuguese version of the Back Pain Attitudes Questionnaire (Back-PAQ-Br) was used to assess participants' beliefs about LBP. Back-PAQ-Br scores between the three groups were comparatively assessed using linear regression models.
results433 participants were analysed in the study (mean age 44.7 ± 12.1 years). People in Brazil hold unhelpful beliefs about LBP (Back-PAQ-Br median score = 112, interquartile range (IQR): 101 to 120). The median and IQR for each group were: no history of LBP 111 (97.5; 119); history of LBP 110 (98; 118); and current LBP 116 (108; 123). People currently experiencing LBP hold more unhelpful beliefs than people with no history of LBP (mean difference = 6.14; 95 CI: 1.63, 10.64) and people with a history of LBP (mean difference = 5.32; 95 CI: 0.81, 9.84).
conclusionParticipants from a middle-income country (Brazil) population hold unhelpful beliefs about LBP irrespective of their LBP status. However, people currently experiencing LBP hold more unhelpful beliefs.
