Temporal analysis of non-communicable diseases and NCD-HIV/AIDS comorbidity in Malawi: A 4-year retrospective study 2020-2022.

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
objectiveNon-communicable diseases are on the increase in the Sub-Saharan region, which is also the epicentre of HIV/AIDS. There is limited published data on trends and forecasts of the comorbidity of non-communicable diseases and HIV/AIDS in low- and middle-income countries. Hence, the aim of the study was to examine current trends and forecasts for non-communicable diseases and non-communicable disease-HIV/AIDS comorbidity.
methodsData on 30,686 patients from 2019 to 2022 were extracted from the non-communicable diseases Mastercards, from 70 health facilities in Malawi, using a form designed and implemented in KoboToolBox. All cases were aggregated to form weekly counts of non-communicable diseases and non-communicable disease-HIV/AIDS comorbidity and visualised using time series plots. Then the data was subset by the prominent non-communicable disease, which was hypertension and hypertension-HIV/AIDS comorbidity weekly counts. Extreme Gradient Boosting (XGBoost), a machine learning model, was used for model fitting, generating predictions, and forecasting.
resultsThe forecasts showed that the counts of cases per week will range from 137 to 185 cases. Then specifically, hypertension and hypertension-HIV/AIDS comorbidity case counts averaged approximately within the range of 111-124 new cases per week from 2023 to 2030. The hypertension-HIV/AIDS comorbidity had forecasts ranging from 2 to 9 new cases per week. Although the number of new case counts per week had a consistent progression, the number of cases was on an increasing trend over time. Therefore, whether cases in general, hypertension and hypertension-HIV/AIDS comorbidity cases, or hypertension-HIV/AIDS comorbidity cases, the counts per week imply cumulatively higher case counts.
conclusionsDespite the consistency in the projection to 2030, there is a need to consider the upward trend of these cases and implement intervention measures such as sensitisation to control the number of cases. Otherwise, Malawi may not be able to achieve SDG3 targets by 2030.
