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

introductionMalaria remains a major public health challenge in India, with transmission dynamics varying widely across ecological, epidemiological, sociobehavioural and health system contexts. Achieving the national malaria elimination target by 2030 requires integrated, context-specific evidence to design effective interventions. This study aims to generate a comprehensive understanding of malaria transmission and factors surrounding it across diverse eco-epidemiological settings in India by assessing malaria burden, identifying determinants of transmission, evaluating health system performance and equity, characterising vector bionomics and insecticide resistance, and examining the influence of environmental drivers. METHODS AND ANALYSIS: This longitudinal, multicentric study will be conducted in collaboration with the national programme in 12 districts spanning 10 states in India, covering a population of around 25 000 individuals representing varied ecological contexts (urban, periurban, rural, forest-foothill and coastal) and malaria endemicity levels. In each district, two clusters (villages) with a population of 1000 individuals will be included. A baseline mass survey will estimate malaria prevalence using bivalent rapid diagnostic tests (RDTs) and blood smear microscopy, with low-density parasitaemia detected by PCR in a subset of RDT-negative samples. Participants will be followed for 1 year, with monthly screening of symptomatic individuals using RDT and microscopy, and testing a subset of asymptomatic individuals to detect subclinical infections. Sociobehavioural data will be collected through structured interviews and household observations, with purposive inclusion of vulnerable groups, pregnant women, migrants, elderly persons, individuals with disabilities and tribal populations to assess equity dimensions through mixed-methods approaches. Health system performance will be evaluated through key informant interviews with programme officials, health workers, patients, private practitioners and traditional healers. Entomological surveillance will document vector species composition, density, infection rates and assessment of susceptibility status and intensity of insecticide resistance to commonly used public health insecticides. Environmental variables, including temperature, rainfall and humidity, will be linked with entomological and epidemiological data to explore spatiotemporal relationships. ETHICS AND DISSEMINATION: The protocol was approved by the Institute Human Ethics Committee of ICMR-Vector Control Research Centre (IHEC 03-0125/N/F). All standard ethical practices will be adhered to. The findings will be shared with stakeholders and published in reputed open-access journals.
