Multiple long-term conditions and their association with quality of life and healthcare utilisation among adults in India: a cross-sectional analysis of WHO SAGE Waves 2 and 3.
Article in BMJ open, 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
objectivesTo examine the prevalence and disease-combination patterns of multiple long-term conditions (MLTCs) among adults in India and their associations with quality of life and healthcare utilisation.
designCross-sectional analysis of two nationally representative survey waves.
settingCommunity-based household survey conducted across six Indian states (Assam, Karnataka, Maharashtra, Rajasthan, Uttar Pradesh and West Bengal), part of the WHO Study on global AGEing and adult health.
participants9116 adults aged 18 years and older in Wave 2 (2015) and 7885 adults in Wave 3 (2019-2020). PRIMARY AND SECONDARY OUTCOME MEASURES: Quality of life, assessed with the 8-item WHO Quality of Life scale (WHOQoL-8, range 0-100), was the primary outcome. Outpatient visits and hospitalisations in the preceding 12 months were the secondary outcomes. Associations with MLTC were estimated using Tobit regression for quality of life and Poisson regression for healthcare utilisation, adjusting for sociodemographic, socio-economic and behavioural factors.
resultsMLTC prevalence rose from 19.2% to 24.4% between waves and was highest among adults aged 60 years and older, women, urban residents and the wealthiest quintile. Hypertension-cataracts, hypertension-arthritis and hypertension-diabetes were the most prevalent dyads. Depression-chronic obstructive pulmonary disease (COPD) and depression-stroke combinations had the poorest quality of life. Physical and functional domains declined most as MLTC increased, while the financial domain remained stable. Compared with adults without chronic conditions, WHOQoL-8 scores fell in a stepwise pattern with one, two and three or more conditions (-2.6, -5.1 and -6.7 points in 2015; -3.3, -5.6 and -7.9 in 2019-2020; all p<0.001). The COPD-stroke combination had the highest outpatient use, and depression-angina the highest hospitalisation rate. Healthcare use rose incrementally with condition count (p<0.001).
conclusionsMLTC are rising in India and are associated with poorer quality of life and higher healthcare use. High-burden combinations, particularly depression-COPD, depression-stroke, COPD-stroke and depression-angina, warrant targeted interventions to improve quality of life and manage rising healthcare demands.
