1 · What the graph read from it

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.

2 · The registry

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

objectiveMedication-related burden (MRB) is a negative experience with medicine, which may impact on psychological, social, physical and financial well-being of an individual. This study describes the development and initial validation of an instrument specifically designed to measure MRB on functioning and well-being-the Medication-Related Burden Quality of Life (MRB-QoL) tool.

methodsAn initial pool of 76-items for MRB-QoL was generated. The link to MRB-QoL survey was sent to a sample of consumers living with at least one chronic medical condition and taking ≥3 prescription medicines on a regular basis. Exploratory factor analysis (EFA) was used to determine the underlining factor structure. Internal consistency (Cronbach's α) and construct validity were examined. The latter was examined through correlation with Medication Regimen Complexity Index (MRCI), Drug Burden Index (DBI) and Charlson's Comorbidity Index (CCI).

results367 consumers completed the survey (51.2% male). EFA resulted in a 31-item, five-factor solution explaining 72% of the total variance. The five subscales were labelled as 'Routine and Regimen Complexity' (11 items), 'Psychological Burden' (six items), 'Functional and Role Limitation' (seven items), 'Therapeutic Relationship' (three items) and 'Social Burden' (four items). All subscales showed good internal consistency (Cronbach's α 0.87 to 0.95). Discriminant validity of MRB-QoL was demonstrated via its correlations with MRCI (Spearman's r -0.16 to 0.08), DBI (r 0.12 to 0.28) and CCI (r -0.23 to -0.15). Correlation between DBI and 'Functional and Role Limitation' subscale (r 0.36) indicated some evidence of convergent validity. Patients with polypharmacy, multiple morbidity and DBI >0 had higher median scores of MRB-QoL providing evidence for known group validity.

conclusionsThe MRB-QoL V.1 has good construct validity and internal consistency. The MRB-QoL may be a useful humanistic measure for evaluating the impact of pharmaceutical care interventions on patients' quality of life. Future research is warranted to further examine additional psychometric properties of MRB-QoL V.1 and its utility in patient care.
