Table 2.
Comparisons of laboratory investigations in different study groups. The table illustrates that there was a statistically significant difference with p-value < 0.05 between the study groups as regards creatinine, urea, ALT, ESR, and HB levels, with a lower mean of creatinine, urea, and ALT among the OA group, and a higher mean of ESR and a lower mean of HB among the RA group. On the other hand, there was no statistically significant difference with a p-value > 0.05 as regards other investigations.
