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

introductionPopulation ageing in Africa is increasing healthcare demands. Hip fractures require multidisciplinary care and are considered an indicator condition for age-related health services. We aimed to estimate current hip fracture incidence in Zimbabwe, compare rates against other regional estimates and estimate future fracture numbers.

methodsAll hip fracture cases in adults aged ≥40 years, presenting to any hospital in Harare over 2 years, were identified. From this, age- and sex-specific hip fracture incidence rates per 100 000 person-years were estimated using 2022 Zimbabwean Census data and compared with South African and Botswanan estimates. Furthermore, using the United Nations population projections, future hip fracture numbers were estimated to 2052 for Zimbabwe.

resultsIn 2022, 1 83 312 women and 1 79 212 men aged ≥40 years were living in Harare (14.9% of the city's population). Over 2 years 243 hip fracture cases, 133 (54.7%) female, mean (SD) age 71.2 (15.9) years, were identified. Most presented to public hospitals (202 [83.1%]) and were fragility hip fractures (211 [86.8%]); high-impact trauma (eg, traffic accidents) was more common in younger men. Presentation delays of >2 weeks were common (37.4%). Incidence rates for adults aged ≥40 years in Harare (observed) and Zimbabwe (estimated) were 33.5 and 53.8/100 000 person-years, respectively. Over age 50, rates increased with age, with the highest rates seen in women aged ≥85 years (704/100 000 person-years). Age-standardised hip fracture incidence rates are broadly comparable between Zimbabwe, Botswana and Black South Africans in those aged 40-69 years; thereafter, rates in Zimbabwean women and men exceed those in Botswana and South Africa. Across Zimbabwe, the number of hip fractures occurring annually is expected to increase more than 2.5-fold from 1709 in 2022 to 4414 by 2052.

conclusionIn Zimbabwe, most hip fractures in adults ≥50 years are fragility fractures, consistent with age-associated osteoporosis; incidence rates exceed those previously reported regionally. Demands on already challenged healthcare systems will increase.
