Open access · cc by · source: Europe PMC
A tailored smartphone EMI for low-SES smokers was highly acceptable and achieved 20% CO-confirmed abstinence at 12 weeks in a small sample.

Key findings
Mean ~102 tailored messages/3 weeks; 97% found messages helpful; 20% (12/59) were biochemically confirmed abstinent at 12 weeks.
Methodology
59 socioeconomically disadvantaged adult smokers used Smart-T for tailored automated messages around a quit attempt, with CO-confirmed point-prevalence abstinence tracked to 12 weeks.
Limitations
Uncontrolled small sample cannot prove efficacy versus standard care alone.
How this study connects
Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
After type 2 diabetes, healthier behaviours still associate with fewer microvascular complications.
Among UK Biobank adults with type 2 diabetes, more low-risk lifestyle behaviours were associated with lower later microvascular complication rates—extending lifestyle scoring from incidence to complications-after-diagnosis.
Scope note — different behaviour — smoking EMI pilot, not T2D lifestyle score
Limits the claim's scope: a different population, assay, or outcome.
Digital tools show mixed proximal effects — logging more is not the same as preventing disease.
Digital tools show mixed proximal endpoints: a step-log app was associated with higher odds of continued daily logging versus matched controls, while a small uncontrolled smoking EMI reported 20% biochemically confirmed abstinence at 12 weeks.
Evidence for the claim as stated.
Randomised activity/diet programmes, observational lifestyle indices, and digital pilots measure different endpoints (minutes walked, zBMI, incident disease, logging, abstinence). Treating them as one efficacy number manufactures agreement that the designs do not support.
Evidence for the claim as stated.
Cessation can be supported with ecological momentary interventions.
An EMI smoking-cessation evaluation tests delivering support in daily life—intervention evidence, not the same as the NHANES association estimate.
Evidence for the claim as stated.
Association ORs for depression, cessation trial/intervention results, and CV disease risk from tobacco should not be treated as one causal chain without designs that can test directionality.

From concept pages' “where studies disagree.” Disagreement means the same question; scope means different assays, populations, or outcomes.
Randomised activity/diet programmes, observational lifestyle indices, and digital pilots measure different endpoints (minutes walked, zBMI, incident disease, logging, abstinence). Treating them as one efficacy number manufactures agreement that the designs do not support.
- Supports · Web program increased older adults’ measured activity in a trial
- Supports · Healthy lifestyle and multimorbidity risk
- Supports · Child-care diet/activity RCT and zBMI
- Supports · Does a step-log app keep people tracking activity?
- Supports · Facebook team walking RCT
