Independent role of alexithymia on weight loss outcomes in obese women: a six month follow-up study.
Article in BMC women's 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
backgroundThe relationship between difficulties in emotion regulation and obesity has received a great deal of attention. This study aimed to investigate whether alexithymia affects the success of weight loss in obese women, and whether this is mediated by depression.
methodsThis prospective longitudinal study was conducted at an obesity centre, where female patients were enrolled in a six-month diet and education programme. At the beginning of the programme, the Toronto Alexithymia Scale (TAS-20) and the Beck Depression Inventory (BDI) were used to assess levels of alexithymia and depression, respectively. Body mass index (BMI) was also calculated. At the end of six months, BMI was calculated again. The mediating role of the depressive symptoms in the association between the alexithymia and the rate of change in BMI(cBMI) was examined using the Process v4.2 package by Andrew F. Hayes, with model 4 being employed. The bootstrap method was used to test the indirect effect.
resultsThe study included 49 obese women. There was a statistically significant negative correlation between cBMI and TAS-20 score at baseline (ρ= -0.756; p < 0.001), whereas there was no statistically significant correlation between BDI score and cBMI (ρ = 0.037; p = 0.802). In the regression model, alexithymia was independently associated with cBMI (p < 0.001), while depressive symptoms were not independently associated with changes in BMI (p = 0.690). The indirect effect of the TAS-20 score on cBMI via depression was not statistically significant.
conclusionHigher levels of alexithymia were associated with poorer weight loss outcomes in obese women, independent of depressive symptom severity.
