An error appeared in the article entitled "Renal Tubular Dysfunction Complicating the Nephrotic Syndrome," by Stickler et al., in Pediatrics, 26:75, 1960. In Figure 7, page 82, the fecal excretion of phosphorus (hatched area) for Period 7 is plotted incorrectly. The value should be 0.109 gm (not 0.6 as shown). The following statement in the text on page 84 is correct: "In Case 2, after the administration of vitamin D (Period 7), 63% of the total intake of phosphorus was excreted in the urine and only 10% of the phosphorus was excreted in the stool."
