The most frequent of these were grade 3 elevation of TB levels (32/7650; RR: 0.003; 95% CI: 0.002–0.005; I2 = 0%; p = .985), ALT (10/7650; RR: 0.001; 95% CI: 0.00–0.002; I2 = 0%; p = .993), AST (18/7650; RR: 0.003; 95% CI: 0.002–0.004; I2 = 0%; p = 1.00), and reduction of haemoglobin (6/2891; RR: 0.002; 95% CI: −0.002–0.005; I2 = 51.01%; p = .106) (Figure 4). Here, GPT is linked to tuberculosis.
