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
Background and objectives Dolutegravir (DTG)-based first line antiretroviral therapy (ART) is preferred globally due to its high efficacy, and tolerability. In India, data on evaluation of its pharmacoeconomic impact with effectiveness and safety remains limited. This study aimed to assess the pharmacoeconomic variables, effectiveness, and safety of the dolutegravir based first line ART regimen among people living with HIV (PLHIV) in south Gujarat. Methods This prospective, and observational study was conducted at an ART centre in a tertiary care hospital. Adults (≥18 yr) receiving first-line ART for ≥6 months were enrolled (n=204) following the informed consent. Pharmacoeconomic outcomes were evaluated using analysis of cost-effectiveness, cost minimisation, cost-utility, and cost-benefit. For effectiveness, CD4 count and plasma viral load (PVL) were recorded at baseline and 6 months. The safety was assessed using causality, severity, and preventability assessment of adverse drug reactions. Results Among 204 participants, 102 received TLD (tenofovir/lamivudine/dolutegravir) and 102 TLE (tenofovir/lamivudine/efavirenz). The TLD regimen demonstrated significantly better cost effectiveness (median CER 45.7 vs. 84.7; P<0.001) and lower mean annual treatment cost [INR (₹)17,074 vs. ₹19,283; P<0.001]. Quality-adjusted life years (QALY) and disability-adjusted life years (DALY) values were comparable between regimens. Both groups showed significant CD4 improvement over 6 months; inter-regimen differences were non-significant (P=0.386). Viral suppression at 6 months was higher with TLD (99% vs. 92.2%; P=0.019). Fourteen ADRs were reported for TLD group. Interpretation and conclusions Dolutegrevir-based regime demonstrated better cost effectiveness, lower annual cost, and more consistent viral load suppression, with comparable immunological recovery and a favourable safety profile, as compared to standard ART regime.
