From: Comparability of HbA1c and lipids measured with dried blood spot versus venous samples: a systematic review and meta-analysis

Figure 2

Individual (solid) and summary (dotted) regression lines showing the associations between results for analyses based upon dried blood spot (DBS) compared to venous (V) samples for haemoglobin A1 c (HbA1 c ) analysed by any method (2A), HbA1 c analysed by specific methods (2B to 2D), triglycerides (2E) and total cholesterol (2E). - Thickness of line increases with sample size. Line length was defined as ±1 standard deviation (SD) of the study (or overall) mean. Where the mean or SD of a study was not available the average for that analysis was used.
