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

Cardiothoracic surgery in South Africa began in Cape Town spreading to the rest of the country, and since the end of apartheid slowly reaching other sub-Saharan African countries. It is a story of brilliant innovators, of the evils of the disease of apartheid but also of what is possible if you are determined and prepared to work hard. The early leaders came from the University of Cape Town (UCT) with Christiaan Barnard, Donald Ross and Rodney Hewitson all in the same class of 1946 with Ben Le Roux and Bob Frater soon after. It is a story of world class professionals in a sea of poverty. The heart transplants performed by Barnard stimulated the whole university and eventually had an effect in raising the standard of medicine in South Africa. Despite the apartheid laws at the time the cardiac unit at UCT was run as multiracial as it was possible at the time with all patients receiving the same care. Apartheid also had an effect on the emigration of many highly talented graduates to other countries. The end of apartheid caused great changes to healthcare in the country, many of great benefit but also some not so good. As UCT influenced the rest of South Africa, the South African medical fraternity can affect the rest of sub-Saharan Africa to the benefit of all its people.
