Temporal trends in cervical cancer incidence and mortality in economically emerging countries, 1992-2021: an age-period-cohort analysis.

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
introductionThe economically emerging countries contributed to over half of the global cervical cancer (CC) burden and are good examples showing how rapid economic growth and health policy change affect the trends of CC burden. This study aimed to analyse the time trends of CC burden across Brazil, Russia, India, China and South Africa (BRICS) and associations with age, period and birth cohort from 1992 to 2021.
methodsData on CC incident cases, deaths, age-standardised incidence rates (ASIRs) and age-standardised mortality rates (ASMRs) were sourced from the Global Burden of Disease Study 2021 to demonstrate the temporal trends of CC burden for BRICS countries from 1992 to 2021. An age-period-cohort model was used to determine the net drift, local drift, longitudinal age curves, as well as period and cohort relative risks regarding CC incidence and mortality.
resultsBetween 1992 and 2021, the ASIR of CC decreased from 16.5 to 15.6 per 100 000 women (-5.5%) and the ASMR declined from 10.1 to 6.7 per 100 000 women (-33.7%) in BRICS. Brazil reported continuous decreases in both CC incidence (net drift: -1.1%, 95% CI -1.1% to -1.0%) and mortality (net drift: -1.7%, 95% CI -1.80% to -1.6%). India also had reduced CC incidence and mortality but experienced worsening period effects from 2012 onwards. Russia and China experienced decreasing trends in mortality yet increasing trends in incidence, and there were apparent unfavourable trends among young and middle-aged women in Russia. South Africa maintained the highest CC incidence (40.0 per 100 000 women, 95% CI 35.0 to 45.6) and mortality (21.3 per 100 000 women, 95% CI 18.8 to 24.1) across the BRICS and had the steepest growth of CC incidence and mortality rates with increasing age.
conclusionDespite an overall decreasing trend of CC burden in BRICS, substantial heterogeneity exists across nations. Identifying country-specific priority groups and tailoring interventions is essential, and the patterns observed have implications for public health strategies applicable not just to BRICS nations but also to many other emerging economies facing substantial CC burden.
