Article Title: Decentralized TB diagnostic testing with Truenat MTB Plus and MTB-RIF Dx vs. hub-and-spoke GeneXpert MTB/RIF Ultra in Mozambique and Tanzania: a cost and cost-effectiveness analysis

doi: 10.1371/journal.pgph.0004724

Figure Lengend Snippet: Health system facility-based cost per participant tested for tuberculosis, comparing point-of-care Truenat MTB assays versus hub-and-spoke Xpert Ultra MTB assays (standard of care, SoC) testing in the TB-CAPT Core Trial. Each segment within each stacked bar corresponds to a distinct cost category, illustrating its proportionate contribution to the total health system expenses for diagnostic testing in each arm of the trial. Training costs were grouped under communication and monitoring & evaluation (CME), while other consumables included sample preparation kits, fuel, personnel protective equipment, and other medical consumables. All costs are reported in 2022 US dollars. For legibility, costs labels are presented for only those categories where the cost is higher than $2.

Article Snippet: The World Health Organization (WHO) Consolidated Guidelines on Tuberculosis (Module 3: Diagnosis - Rapid Diagnostics for Tuberculosis Detection) recommend three primary molecular methods for initial TB diagnosis with concurrent drug-resistance detection: (1) Xpert MTB/RIF and Xpert MTB/RIF Ultra assays (Cepheid, USA), (2) Truenat MTB, MTB Plus, and MTB-RIF Dx assays (Molbio Diagnostics, India), and (3) moderate complexity automated nucleic acid amplification tests (NAATs) [ ].

Figure Lengend Snippet: Design and evaluation of gRNAs for the CRISPR-Cas14a MTB RIF/INH platform to detect RIF- and INH-resistant mutations. ( A ) ssDNA substrates including wild-type (WT) and mutated versions were used. Fluorescence intensity was measured at 2-min intervals over a period of one hour. ( B ) After 60 min, the fluorescence intensities among different gRNAs were compared. Statistical significance of the differences was evaluated using the unpaired t-test ( n = 3 technical replicates; bars represent mean ± S.E.M, ** p < 0.01, *** p < 0.001, **** p < 0.0001)

Figure Lengend Snippet: Evaluation of the LOD and specificity of the CRISPR-Cas14aMTB RIF/INH platform for detecting MTBC. ( A ) The fluorescence levels of the CRISPR-Cas14aMTB RIF/INH platform were measured across a dilution series of Mtb H37Rv genomic DNA. A heatmap was generated to display the signals of the platform for each individual gRNA. ( B ) Fluorescent signals were transformed into to a binary test result using a cut-off signal that was more than 6 standard deviations above the no template control. The LOD was determined by performing six replicate reactions at each dilution. ( C ) The specificity of each individual gRNA was determined using DNA from six common NTM strains, H37Rv strain DNA, and E. coli DH5α. Negative controls, where reactions were performed without DNA. For LOD determination, six technical replicates were executed, and for the specificity test, three technical replicates were performed. The bars in the graphs represent the mean values ± standard error of the mean (S.E.M), with statistical significance indicated as follows: * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001
