Meta-analysis of summary statistics versus individual participant-level data of trials with binary outcomes
No full textDissertation (MSc (Advanced Data Analytics))--University of Pretoria, 2022.In this essay we will consider the meta-analysis of summary statistics versus individual participant-level data of trials with binary outcomes. Numerous techniques will be considered to essentially determine, both theoretically as well as numerically, by the use of real data analysis, whether or not, in certain instances, analyzing individual participant data (IPD) from all investigations undoubtedly gains efficiency over combining summary statistics from each study in a binary setting. We will be considering both the one-step as well as two-step meta-analysis, with the focus being mainly on the standard fixed-effects model and partially on the random-effects model. An application of two different clinical studies will be considered. The first study is called the Cannon (Cannon et al., (2006)[13]) Cardiovascular Clinical Trials which consists of four clinical studies. The second study is called the Bacillus Calmette-Guerin Vaccine Study which consists of a total of 13 clinical studies. We observed that a meta-analysis of summary data is more similar to a meta-analysis of IPD data for the first study, but different for the second study. This is due to the fact that the number of studies
are small in both studies. Therefore the asymptotic equivalence should be cautious when the sample size is small and the number of studies is small. In this case, the estimation of the between study variance will be very unstable which will lead to a different conclusion between a meta-analysis of summary statistics (SS) and a meta-analysis of individual participant-level (IPD) data.This work is based upon research supported by the National Research Foundation, South Africa (South Africa DST-NRF-SAMRC SARChI Research Chair in Biostatistics to Professor Ding-Geng Chen, Grant number 114613).

Come tradurre Milo De Angelis
No full textThe section presents the Chinese translation of four poems by Milo De Angelis, who is
among the best Italian contemporary poets. The poems are taken from the collection "Incontri e agguati" (Mondadori, 201 5). The texts are both in Italian and Chinese in parallel
text. Yang Lin, with the help of Geng Jiang (Chinese musician and poet), took care of the
translation.
The section opens with a note made by the translation group that analyses the processes
of the transposition of the dense poetic language of De Angelis into the Chinese language.
There follows an enlightening letter from Milo De Angelis to the translation group. The four
poems in Chinese and Italian complete the section

The specific name is an anagram of azimi, a similar species in this genus. Comments. Encarsia imiza resembles E. azimi Hayat in having similar body colour and the presence of internal sculpture in the cells forming the reticulation on the thoracic dorsum, but can be separated from the latter by the following characters: occiput largely yellow except for a brownish patch on each side of foramen (vs occiput completely brownish); mesosoma largely brownish-yellow (vs brown); all legs yellowish (vs fore and hind coxae brown basally); ovipositor 0.56–0.58× as long as mid tibia and basitarsus combined (vs 0.76×); gaster pale yellow (vs pale yellow with T1 across base dark brown).Published as part of Geng, Hui & Li, Cheng-De, 2017, Three new species of the Encarsia inaron (Hymenoptera: Aphelinidae) species group from China with a key to Chinese species, pp. 208-222 in Zootaxa 4306 (2) on page 215, DOI: 10.11646/zootaxa.4306.2.2, http://zenodo.org/record/84373
