“…The epidermal ridges and their drawings are developed early in life and never changed throughout the individual’s lifetime [ 5 ]. It is well-known that the drawing of ridges on finger and palmar areas varies in people and it depends on individual’s genetic profile [ 6 ]. In addition, dermatoglypic patterns are investigated to apply in disease-related risk assessment due to an obvious association between morphological and genetic characteristics [ 7 ].…”

Dermatoglypic patterns are extensively investigated to apply in disease-related risk assessment due to an obvious association between morphological and genetic characteristics. In the current study, we aimed to determine whether the fingerprint and palmar patterns vary between case population with schizophrenia and general population. A cross sectional study was conducted in people diagnosed with schizophrenia (cases) and a control population between 2016 and 2019. In this study, 252 people were participated. Ink and paper method was used to evaluate the difference of fingerprints palm prints between patients with schizophrenia and participants in control group.93 participants were analyzed in schizophrenic group and 142 participants were investigated in the control group. The percentage of arches on the right ring finger was significantly different between the schizophrenic patient group and control group (p = 0.011). The whorl pattern type (U-W-U-W-W-W-W-U-W-U) was dominantly observed in both of the schizophrenic patient group and control group. A-B ridge count in schizophrenic patient group and control group produced a markedly significant difference (p<0.05). Interestingly, a strong significant difference was produced in comparing of A-B ridge count in catatonic schizophrenia group with residual schizophrenia group (p<0.005). In comparison, index of pattern intensity in control group was slightly higher than that in schizophrenic patient group. Taking together, these results showed that the dermatoglypic characteristics might be a valuable tool to describe the nature of schizophrenia and its clinical subtypes and further studies are needed in clinical application.

“…The effect size of parents should play one of four roles in a child according to Mendelian pattern [17], therefore, we propose that an effect size (CRC): less than 0.25 indicates a weak intensity factor (which can be understood as one of more than four factors playing roles in a disease under the standard model); ranging from 0.25 to 0.50 indicates a moderate intensity factor (which implies that one or two of three factors plays a role in a disease); and over 0.50 indicates a high intensity factor (which implies that one factor mainly plays a role in a disease); values in excess of 0.75 indicate only one observed factor plays a role in a disease.…”

Background: To determine the effect size of an observed factor for a disease by using consistency in a cohort study (CRC) for evaluating practical significance of differences between two groups of case-control design. Methods: A model of multiple pathogenic factors was established by analyzing the number and distribution of observed factors in a study population. The difference in the incidence between two groups (exposed and unexposed) was calculated according to the model as CRC. The relationship of Youden’s index and true and false-positive ratio (TFR) in case-control design were observed with CRC. Results: The CRC was able to correctly reflect the number of factors combined in the models, and therefore, indicates that CRC is a reasonable indicator of effect size. Difference scores <0.25 indicate that one of four or more factors plays a role in a disease; scores >0.50 indicate one of two factors plays a role in disease and implies a high intensity level of the factor. TFR could correctly reflect CRC. Accordingly, a factor with an effect size (i.e., TFR) less than 6.0 should not be considered a clinically significant factor, even if the observed difference is statistically significant. Conclusions: A CRC over 0.25 OR TFR over 6.0 is suggested as an indicator of a substantial effect size.

Penelitian variasi pola sidik jari Suku Kaili dan Toraja telah dilakukan di Kota Palu dan Kabupaten Sigi, Sulawesi Tengah. Tujuan dari penelitian ini adalah untuk mengetahui variasi pola sidik jari, Indeks Dankmeijer, Indeks Furuhata dan jumlah total sulur masyarakat Suku Kaili dan Toraja. Probandus dibagi menjadi tiga kelompok yaitu Kaili Da’a (rumpun Suku Kaili yang memiliki karakteristik fenotip menyerupai Ras Australomelanesoid), Suku Kaili lainnya serta Suku Toraja yang tergolong ras Mongoloid. Sampel sidik jari diambil menggunakan metode purposive sampling dengan total 180 probandus, terdiri atas 60 orang (30 laki-laki dan 30 perempuan) di setiap kelompok suku. Kesepuluh ujung jari tangan probandus digosok dengan kertas yang berisi gosokan pensil 4B, sidik jari diambil menggunakan selotip bening, kemudian selotip ditempelkan pada formulir probandus. Analisis data dilakukan dengan uji Chi-square dan uji Student-t. Hasil analisis sidik jari menunjukkan empat pola sidik jari ditemukan pada Suku Kaili dan Toraja. Frekuensi whorl tertinggi ditemukan pada Suku Toraja (50,17%), sedangkan Kaili Da'a dan Kaili lainnya memiliki frekuensi loop yang lebih tinggi. Analisis tipe whorl menunjukkan simple whorl merupakan tipe yang paling banyak ditemukan di ketiga populasi. Selanjutnya double loop whorl dan yang paling sedikit frekuensinya adalah central pocket whorl. Nilai Indeks Furuhata pada masyarakat Suku Toraja, Suku Kaili dan Kaili Da’a secara berturut-turut adalah 102,73; 57,37; dan 95,06 sedangkan nilai Indeks Dankmeijer secara berturut-turut adalah 1,99; 5,61; dan 2,77. Jumlah rata-rata total sulur pada masyarakat Suku Toraja, Suku Kaili dan Kaili Da’a secara berturut-turut adalah sebesar 134; 128,08 dan 133,56.
