Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationIndividuals with dental caries lesions; human primary or permanent teeth assessed on occlusal, approximal, or smooth surfaces17 studies; 5 in vivo, 11 in vitro, 1 mixed design; permanent (13) and primary (4) dentition; sample sizes 40-627 teeth (in vivo) and 21-400 teeth (in vitro)
InterventionQuantitative light-induced fluorescence (QLF) technology (delta F and/or delta R parameters)QLF devices: QLF-Clin, Inspektor Pro, QLF-D, Qraypen C; parameters delta F and delta R
ComparisonA clearly defined, appropriate reference standard (e.g., ICDAS visual examination, histology, radiography)Reference standards: histology, ICDAS visual examination, radiography/bitewing, ADA classification
OutcomesDiagnostic validity: sensitivity, specificity, and area under the ROC curve (AUC), derived from 2x2 tables (TP/FP/TN/FN)Pooled sensitivity/specificity via HSROC (MetaDTA): in vivo occlusal 0.86/0.82 (4 studies); in vivo proximal 0.74/0.82 (4); in vitro occlusal 0.83/0.74 (5); in vitro proximal 0.83/0.74 (3). Per-study AUC 0.59-0.99. AUC not pooled; no confidence intervals reported in text or Table 4
Study designsIn vivo (clinical) and in vitro (laboratory) diagnostic accuracy studies; primary and permanent dentition17 included; occlusal (11), proximal (5), smooth (1) surface studies; meta-analysis in 9 studies (4 in vivo, 5 in vitro)
TimingNot specified (cross-sectional diagnostic accuracy)Not specified
