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
objectiveNegative bias towards patients with mental illness contributes to worsened healthcare outcomes. However, few data exist on interventions to decrease bias. In this study, the authors examined the impact of brief patient exposure on first-year medical student perceptions of psychiatry.
methodsIn 2023, two townhalls were introduced to the psychiatry course for first-year medical students at Indiana University School of Medicine. Participants were surveyed before and after the course using the Mental Illness: Clinician's Attitudes version 2 (MICA-2), with higher scores indicating more negative bias. Pre- and post-course scores were compared with paired t-tests. Level of pre-course bias in years with townhalls (2023 and 2024) was compared to the year without townhalls (2022) with an unpaired t-test. Impact of townhalls was assessed by comparing 2022 data to 2023 and 2024 with repeated measures analysis of variance (ANOVA).
resultsResponse rates ranged from 22.5 to 32.0%. The combined 2023 and 2024 pre- and post-course MICA-2 means were 36.5 (SE 0.6) and 34.8 (SE 0.6), respectively. The pre-course means were not significantly different from 2022's, indicating a consistent level of baseline bias (t(236) = 0.11, p = 0.92). Repeated measures ANOVA indicated change attributed to the course was significantly less in years with townhalls (2023 and 2024) compared to the year without (2022; F = 4.04, p = 0.045).
conclusionsContrary to the hypothesis, added patient volunteer exposure resulted in less reduction in bias compared to the year without such exposure. These findings suggest increased complexity in reducing bias; timing and context of patient exposures may be important determinants of effect on bias.
