Biplab Sarkar This editorial describes the growth pattern of female radiation oncologists (FRO) in India and the prediction of gender equality through a mathematical formulation. Among the countries in South Asia, India has the largest population of radiation oncologists (RO), a total of 3,763: 1,286 female and 2,477 male radiation oncologists (MROs), and they are registered with the Association of Radiation Oncologists of India (AROI). The data were analyzed to find the differential and cumulative growth pattern of the FROs and MROs and predict gender equality in radiation oncology. The cumulative growth rate indicates the total number of FROs and MROs by end of every year. Differential growth rate indicates the differential increase in the number of FROs and MROs for a particular year. Annual cumulative and differential growth patterns were plotted as a function of the time, and an analytical functional form was fitted to predict the future growth pattern and achievement of gender equality. AROI registration of FROs and MROs for 2013-2020 were as follows: FRO: MRO 2013-54: 102, 2014-99: 162, 2015-77: 148; 2016-86: 143, 2017-110: 110, 2018-116: 151, 2019-121: 152, 2020 (October)-129: 110. Differential growth pattern between 2013 and 2020 with the average incremental growth rate for FROs and MROs were 12.7 ± 14.8% and 2.1 ± 32.0%. Differential growth rate FRO fits in a power-law exponent 58.6 ×(Power0.3695), where MRO growth pattern showed a saturation [4.7ln(×) + 128.5] . Gender parity among Indian radiation oncologists is likely to be achieved by end of 2027. The present density of FRO in India 34.1% is high compared to developed countries such as the United States (≈26%). It is a big leap for the Indian radiation oncology society tending toward gender parity.
比普拉布·萨卡尔 这篇社论描述了印度女性放射肿瘤学家(FRO)的增长模式,并通过数学公式预测性别平等情况。 在南亚国家中,印度的放射肿瘤学家(RO)人数最多,共有3763人,其中女性放射肿瘤学家1286人,男性放射肿瘤学家(MRO)2477人,他们均在印度放射肿瘤学家协会(AROI)注册。对这些数据进行分析,以找出FRO和MRO的差异增长模式和累积增长模式,并预测放射肿瘤学领域的性别平等情况。累积增长率表明每年年底FRO和MRO的总数。差异增长率表明特定年份FRO和MRO数量上的差异增长。将年度累积和差异增长模式绘制成时间的函数,并拟合出一种分析函数形式,以预测未来的增长模式和性别平等的实现情况。 2013 - 2020年FRO和MRO在AROI的注册情况如下:2013年 - FRO:54人,MRO:102人;2014年 - FRO:99人,MRO:162人;(此处原文有误,推测是2015年 - FRO:77人,MRO:148人;2016年 - FRO:86人,MRO:143人;2017年 - FRO:110人,MRO:110人;2018年 - FRO:116人,MRO:151人;2019年 - FRO:121人,MRO:152人;2020年(10月) - FRO:129人,MRO:110人。2013年至2020年的差异增长模式以及FRO和MRO的平均增量增长率分别为12.7 ± 14.8%和2.1 ± 32.0%。FRO的差异增长率符合幂律指数58.6×(幂次0.3695),而MRO的增长模式呈现饱和状态[4.7ln(x) + 128.5]。印度放射肿瘤学家之间的性别平等可能在2027年底实现。 印度目前FRO的占比为34.1%,与美国等发达国家(约26%)相比是较高的。这对印度放射肿瘤学协会迈向性别平等来说是一个巨大的飞跃。 (注:原文中2014年数据格式疑似有误,按照逻辑进行了修正后翻译)
